Ibn al Jawzi رحمه الله said,

"You are the most precious creature to Allah, so be content with what Allah has decreed for you, because he who loves never questions or accuses the one he loves.

The Grace of Allah upon you in all that He created for your sake is as clear as daylight, so how could you imagine that He would neglect when you are at the roof of it all?”

Mu'tamir ibn Sulayman said: I visited my father when I was very sad.

He said: What’s wrong?

I said: A friend of mine died.

He replied: Did he die on the Sunnah?

I said yes.

He said: Then don’t fear for him!

The Prophet said: None of you should ever die except while assuming the best about Allaah.

Source: Saheeh Muslim (no. 5125)

This means: You should think that He’ll have mercy on you and forgive you.

Ḥasan al-Baṣrī رحمه الله used to say: "The grave eats up the bones and meat, but doesn't eat up the Iman.

[العزلة لابن أبي الدنيا ٢٠٤]

‎Shaykh as-Sa’dī رحمه الله said in Tafseer of this Āyah: “For indeed the Jāhil (ignorant one) utters speech which ‎has no benefit in it and he is the one WHO MAKES FUN OF PEOPLE.”
