Maturity is being able to have your opinions and beliefs challenged, without feeling personally challenged or attacked. The world is a diverse place, it’s impossible to have everyone agree with you.

The Messenger of Allah (ﷺ) said:

If anything befalls you, do not say ‘If only I had done (such and such), the such and such would have happened,’ - rather say: ‘Allāh has decreed and what He wills He does,’ - for ‘if only’ opens the door to the work of the shaytān

[Ṣaḥih Muslim]

‏ليس كل ما نفقده يعُد خسارة؛
Not everything we lose is a loss

قد يريد الله النعمة بخير منها
Allāh ﷻ may want a blessing better than it

‏قاعدة :
لا شيء يستحق الحزن والندم في حياتك ، سوى تقصيرك في طاعة الله ﷻ..
Rule:

Nothing in your life is worth being sad/regretful over, except for your deficiencies in your obedience to Allāh ﷻ.

Self-evaluation: How Can I Know if I am Pious?

Shaqīq bin Ibrāhīm رحمه الله mentions some indicators.

Don’t ever feel arrogant if you see someone not on the straight path of guidance and obedience, rather be grateful that Allah guided you and acknowledge that only He, Allah guided you, and if wasn’t for his guidance you would have never prayed, fasted or sought knowledge.

Allah tells about the people of paradise that they say:

وقالوا الحمد لله الذي هدانا لهذا وما كنّا لنهتدي لولا أنْ هدانا الله

“And they said: All praises to Allah who has guided us to this, and we would never have been guided if Allah had not guided us.” (al-A’raaf: Verse 43)

The Sahabah would recite these lines of poetry whilst digging the trenches of Khandaq:

اللَّهُمَّ لَوْلَا أنْتَ ما اهْتَدَيْنَا ... ولَا تَصَدَّقْنَا ولَا صَلَّيْنَا

“O Allah, if it was not for you we would never have been guided, nor would we have prayed or given charity..”

So if Allah has blessed you with guidance then be grateful for it!

By Allah do not trade it for anything! In the waves of doubts & desires hold firm to this guidance.

By Allah, the strangeness of holding firm to the light of Islam has never been more fought.

How to do work of Deen:

1) Plan more, and do not look at your resources

2) Work more, and do not depend on people

3) Do more, and do not worry what others think

Cry to Allah to accept.
When Allah accepts, Allah assists.

[Mufti Ismail Moosa]

Advice to avoid sins, and to live a pure life in this world.

Taqwa and Allāh ﷻ consciousness does not mean that one will not sin. That is impossible. It means being remorseful and making sincere tawbah and istighfaar in the event one slips and commits a sin. A person gets closer to Allāh ﷻ through this.

Mufti Muajul

Don't ruin your current peace of mind by overthinking about things that have not occurred. Don't create rifts where there is stillness. The human mind is created in a way that it cannot handle too much at once so focus on the task at hand and take each moment as it comes.

Don't ruin a morning coffee, a blessed Friday, or a moment with a loved one by worrying about something that the shaytan manufactured in order to make you sad. There is always something good to turn to.

“Be observant of Allāh ﷻ in secret and in public, turning between fear and hope. Turn to your Lord completely, and let your heart be filled with love of Him, your tongue with His remembrance, and be happy with His rulings and wisdoms”.

— Sharh Hilyah Talibul ilm, Ibn Uthaymeen رحمه الله

The Story Of Abū Ṭalḥah رضي الله عنه, coming back to his house, but not knowing that his Child had passed away.

SubḥānAllāh this is so incredible.
