Mankind should not forget about Allah ( Surah Al-Infitar 82: 6)

Mankind should not forget about Allah

Allah says,

O man! What has made you careless about your Lord, the Most Generous.  This is a threat. It is not an attempt to get a reply as some people mistakenly think. They consider it as if the Most Generous is asking them so that they will say, "His honor deceived him (or made him careless of his Lord).'' rather the meaning of this Ayah is, "O Son of Adam! What has deceived you from your Lord, the Most Generous -- meaning the Most Great -- so that you went forth disobeying Him, and you met Him with that which was unbefitting.'' This is similar to what has been reported in the Hadith,

Allah will say on the Day of Judgement: "O Son of Adam! What has deceived you concerning Me O Son of Adam What was your response to the Messengers''   Al-Baghawi mentioned that Al-Kalbi and Muqatil said, "This Ayah was revealed about Al-Aswad bin Shariq who struck the Prophet (Sallallahu Alayhi wa Sallam) and he was not punished in retaliation. So Allah revealed,

What has made you careless about your Lord, the Most Generous''
