قال شيخ الإسلام رحمه الله:

وليس من شرط المتقين ونحوهم أن لا يقع منهم ذنب بل من تاب من ذنوبه دخل في المتقين."

Shaykh al-Islam ibn-Taymiyyah رحمه الله said:

It is not conditional for the pious and their likes that they do not fall into sin, rather whoever repents from his sins enters into the pious.

[Minhaj as-Sunnah (2/82)]

قال رسول الله صلى الله عليه وسلم قال: كل ابن آدم تأكل الأرض إلا عجب الذنب، منه خلق
وفيه يركب.

The Messenger of Allāh ﷺ said: “All of the son of Ādam is eaten by earth (after death) except for the tail-bone, from it he was created and on it (he) will be reconstructed (on the Day of Judgement).”

[سنن أبي داود ٤٧٤٣، صححه الألباني]

قال الامام البخاري:

وكنت أختلف إلى الفقهاء بمرو، وأنا صبي، فإذا جئت أستحي أن أسلِّم عليهم، فقال لي مؤدب من أهلها: كم كتبت اليوم؟ فقلت: اثنين، وأردت بذلك حديثين، فضحك من حضر المجلس، فقال شیخ منهم: لا تضحكوا، فلعله يضحك منكم يوماً.

Imam Al-Bukhari said:

"I cautiously differed with the jurists [scholars} while I was a young boy, so when I came {to the gathering] I was too shy to greet them [with salaam} so one of the teachers said to me: "How many have you written today?" So I said: "Two", by that I intended two ahadith. Then those who attended the gathering started to laugh {at Bukhari], then a Shaykh amongst them said: "Don’t laugh at him, for perhaps he will laugh at you one day."

[Siyar A'laam 12/401]

حَدَّثَنَا سُلَيْمَانُ أَبُو الرَّبِيعِ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، قَالَ حَدَّثَنَا نَافِعُ بْنُ مَالِكِ بْنِ أَبِي عَامِرٍ أَبُو سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏آيَةُ الْمُنَافِقِ ثَلاَثٌ إِذَا حَدَّثَ كَذَبَ، وَإِذَا وَعَدَ أَخْلَفَ، وَإِذَا اؤْتُمِنَ خَانَ."
•••
The Prophet (ﷺ) said, "The signs of a hypocrite are three:

1. Whenever he speaks, he tells a lie.
2. Whenever he promises, he always breaks it (his promise).
3. If you trust him, he proves to be dishonest. (If you keep something as a trust with him, he will not return it).”

[Sahih al-Bukhari 33]

لله ملك السموات والأرض، واستقرض منك حبة فبخلت بها، وخلق سبعة أبحر وأحب منك دمعةً فقحطت عينك بها.
•••
To Allaah belongs the kingdom of the heavens and the earth, yet He asks a loan from you (i.e. giving charity) but you are stingy. He created the seven seas, but He loved a tear from you (out of fear of Him) but your eyes were tearless.

‏ما معنى العبادة؟
هي اسم جامع لكل ما يحبه الله ويرضاه من الأقوال
والأعمـال الظاهرة والباطنة
•••
What is Worship?
Worship (al-’Ibaadah) is a comprehensive term covering everything that Allaah loves and is pleased with – whether saying, or actions, outward and inward.

والرب هو المعبود، والدليل ‏قوله تعالى:
•••
The word Rabb (the Lord) is the One who is worshipped. The proof for this is Allaah's saying:

يٰۤاَيُّهَا النَّاسُ اعۡبُدُوۡا رَبَّكُمُ الَّذِىۡ خَلَقَكُمۡ وَالَّذِيۡنَ مِنۡ قَبۡلِكُمۡ لَعَلَّكُمۡ تَتَّقُوۡنَ ۙ‏ ﴿2:21﴾ الَّذِىۡ جَعَلَ لَـكُمُ الۡاَرۡضَ فِرَاشًا وَّالسَّمَآءَ بِنَآءً وَّاَنۡزَلَ مِنَ السَّمَآءِ مَآءً فَاَخۡرَجَ بِهٖ مِنَ الثَّمَرٰتِ رِزۡقًا لَّـكُمۡ ۚ فَلَا تَجۡعَلُوۡا لِلّٰهِ اَنۡدَادًا وَّاَنۡـتُمۡ تَعۡلَمُوۡنَ ‏ ﴿2:22﴾
•••
O mankind! Worship your Lord who created you and those before you, so that you may be dutiful to Him. He is the one who made the earth a resting place for you, and the sky as a canopy, and sent down water from the sky and brought forth therewith fruits as a provision for you. So do no set up rivals with Allaah in worship knowingly.
[Surah Al-Baqarah: 21-22]

قال ابن كثير رحمه الله تعالى: "الخالقُ لهذهِ الأشياءِ هو ‏المستحقُ للعِبَادة."
•••
Ibn Katheer, may Allaah have mercy on him, said: “The Creator of these things is the One who truly deserves to be worshiped."

كما قال ابن القيم في النونية:
وعباد الرحمنِ غاية حبهِ
مع ذُل عابده هما قطبان ‏
•••
As was said by Ibn al-Qayyim in An- Nooniyyah:
And worship of the Most Merciful One is to have the utmost love of Him,
Along with humble submission of his servant, they are the two pivots.

وأنواع العبادة التي أمر الله بها مثل الإسلام، والإيمان، والإحسان
•••
And the types of worship which Allaah has commanded such as al-Islām, and al-Imān and al-Ihsān.

‏هذه ‏الأنواع الثلاثة أعظم أنواع ‏العبادات
•••
These three types are from the greatest types of worship.

ما معنى الإسلام؟
الإسام هو الإستسلم الله بلتوحيد والأنقياد له بالطاعة والبراءة من الشرك و أهله
•••
What is al-Islām?
[al-Islām is to submit/surrender yourself to Allāh with Tawḥīd, and to submit/surrender yourself to Allāh with obedience, and to make barāʾah (free yourself) from shirk and it’s people.

فأركان الإسلام خمسة:
١- شهادة أن لا إله إلا الله وأن محمدا رسول الله
٢- وإقام الصلاة
٣- وإيتاء الزكاة
٤- وصوم رمضان
٥- وحج بيت الله الحرام.
•••
And the pillars of Islām are 5:
1- The testification that none has the right to be worshipped except Allaah, and that Muhammad is the Messenger of Allāh
2- Establishing the Prayer
3- Giving the Zakāt
4- Fasting Ramadan
5- Performing Hajj to Allah’s Sacred House.

ما ‏معنى الإيمان؟

وأما الإيمان في الشرع: فهو كما فسره أهل السنة والجماعة: قول باللسان، واعتقاد بالقلب، وعمل بالجوارح، يزيد بالطاعة، وينقص بالمعصية.
•••
What is al-Imān?

As for [the meaning of] Imān in the legislation, then it is as explained by the people of the Sunnah and Jamaa`ah: Speech of the tongue, belief of the heart, and action of the limbs. It increases with obedience, and it decreases through sin.

ولا يكفي القول باللسان والاعتقاد بالقلب، بل لا بد من العمل بالجوارح أيضا، لا بد من أداء الفرائض وتجنب المحرمات، فيفعل الطاعات ويتجنب المحرمات، كل هذا من الإيمان.
•••
And speech upon the tongue, and belief in the heart will not suffice, rather there must be action on the limbs also, and carrying out the obligatory duties is essential, and avoiding the prohibitions. So the person does the acts of obedience and he avoids the forbidden acts, all of this is from al-Imān.

وأركانه ستة:
أن تؤمن بالله
وملائكته
وكتبه
‏ورسوله
واليوم الآخر
وتؤمن بالقدر خيره وشره.
•••
The pillars of Imān are 6:
-To have Imān in Allah
-His Angels
-His Books
-His Messengers
-The Last Day
-Imān in the Decree, the good of it, and the bad of it.

‏ما معنى الإحسان؟

المرتبة الثالثة : الإحسان، ‏ركن واحد وهو:
"أن تعبد الله كأنك تراه فإن لم تكن تراه فإنه يراك"
•••
What is al-Ihsān?

It is a single pillar and it is:
That you worship Allaah as if you were seeing Him, and even though you do not see Him, He certainly sees you.

الإحسان على مرتبتين:

‏المرتبة الأولى: وهي أن تعبد الله كأنك تراه من شدة اليقين والإيمان، كأنك ترى الله عز وجل عيانًا.

والمرتبة الثانية: أن تعبد الله وأنت تعلم أنه يراك ويطلع عليك، فلا تعصيه ولا تخالف أمره سبحانه وتعالی.

•••
al-Ihsān is of two levels:

The level of witnessing with the heart: It is that you worship Allaah as if you are seeing Him from the strength of certainty and Imān. It is as you are seeing Allaah, the Mighty and Majestic, with your eyes.

The second level: It is that you worship Allaah knowing that He sees you and observes you, therefore, you do not disobey Him and contradict His command, He the Perfect and Most High.

هذه مرتبة الإحسان وهي أعلى مراتب الدين، من بلغها فإنه بلغ أعلى مراتب الدين ، وقبلها مرتبة الإيمان، وقبلها مرتبة الإسلام.
•••
This is the level of al-Ihsān and it is highest of the levels of the religion. Whoever reaches it has reached the highest of the levels of the religion. Before it is the level of al-Imān, and before that is the level of al-Islām.

اِنَّ اللّٰهَ مَعَ الَّذِيۡنَ اتَّقَوْا وَّالَّذِيۡنَ هُمۡ مُّحۡسِنُوۡنَ
•••
Allāh is with those who fear Him and are dutiful to Him; and He is with those who are people of ihsaan.
[16:128]

‏قال رسول الله صلى الله عليه وسلم:
ما من أيام العمل الصالح فيها أحب إلى الله من هذه الأيام‏ - يعني أيام العشر - قالوا‏:‏ يا رسول الله ولا الجهاد في سبيل الله‏؟‏ قال‏:‏ ‏"‏ولا الجهاد في سبيل الله، إلا رجل خرج بنفسه، وماله فلم يرجع من ذلك بشيء‏.
•••
The Messenger of Allāh (ﷺ) said:
“There are no days during which the righteous action is more pleasing to Allāh than these days (i.e., the first ten days of Dhul-Ḥijjah)." He was asked: "O Messenger of Allāh, not even Jihad in the Cause of Allāh?" He (ﷺ) replied, "Not even Jihad in the Cause of Allāh, except in case one goes forth with his life and his property and does not return with either of it.”

[Al-Bukhāri ]

وَلَن تَرْضَىٰ عَنكَ ٱلْيَهُودُ وَلَا ٱلنَّصَٰرَىٰ حَتَّىٰ تَتَّبِعَ مِلَّتَهُمْ ۗ قُلْ إِنَّ هُدَى ٱللَّهِ هُوَ ٱلْهُدَىٰ ۗ وَلَئِنِ ٱتَّبَعْتَ أَهْوَآءَهُم بَعْدَ ٱلَّذِى جَآءَكَ مِنَ ٱلْعِلْمِ ۙ مَا لَكَ مِنَ ٱللَّهِ مِن وَلِىٍّ وَلَا نَصِيرٍ ﴿١٢٠﴾ 
•••
“Never will the Jews nor the Christians be pleased with you (O Muhammad) till you follow their religion. Say: ‘Verily, the Guidance of Allaah (i.e. Islamic Monotheism) that is the (only) Guidance.’ And if you (O Muhammad) were to follow their (Jews and Christians) desires after what you have received of Knowledge (i.e. the Qur’aan), then you would have against Allaah neither any Wali (protector or guardian) nor any helper”

[al-Baqarah 2:120]

قال رسول الله صلى الله عليه وسلم: كيف أصبحت يا فلان؟ قال: أحمد الله إليك يارسول الله ,فقال رسول الله صلى الله عليه وسلم : هذا الذي أردت منك.

The Prophet ﷺ asked a man: “O so and so how are you this morning?”, he said: “Aḥmadullaahu Ilayk (I praise Allāh to you) O Messenger of Allāh.”, so the Prophet ﷺ said: “This is what I wanted (to hear) from you.”
