Such was their stance toward them while they were still alive—so what, then, after they have died?!

Al-Bukhārī (1/120, European ed.) and Muslim (8/221) narrate from Ibn ʿUmar that, when the Messenger of Allah ﷺ passed by al-Ḥijr, he said:
“Do not enter the dwellings of these people who were punished unless you are weeping; if you are not weeping, then do not enter them, lest what befell them befall you.”

19 – “Do not enter the dwellings of these people who were punished unless you are weeping; if you are not weeping, then do not enter them, lest what befell them befall you.” (He then drew his cloak over his face while still on his mount.) (From Ibn ʿUmar.)

Aḥmad also transmitted it (2/9, 58, 66, 72, 74, 91, 96, 113, 137); the additional wording is his.

Ṣiddīq Khan headed this ḥadīth in Nuzul al-Abrār (p. 293) with: “Chapter: Weeping and fear when passing by the graves of the wrongdoers and the sites of their destruction, manifesting one’s neediness before Allah Most High, and warning against heedlessness of that.”

I ask Allah, exalted is He, to grant us understanding of our religion and to inspire us to act upon it. Surely, He is All-Hearing, Ever-Responsive.

20 – “Will you not fear Allah regarding this animal that Allah has placed in your care? It has complained to me that you keep it hungry and exhaust it.”
