Commendation of Inhabitants of Paradise:

Hazrat Anas Bin Malik رضی اللہ عنہ stated that Hazrat Muhammad ﷺ­ said “People were in rows on the Day of Judgment that an infernal will pass by a man and say, Oh someone! Don’t you remember that day when you asked for water and I gave you a sip. The Holy Prophet said so that inhabitant of paradise will commend for this infernal, and a man will pass by and say don’t you remember that day when I gave you water to purge or clean yourself, therefore he will commend for him. In other saying it is that the infernal will say Oh someone! Don’t you remember that day when you had sent me for that work and I went at your request (to do it). Therefore, he will commend for him. (sunan Ibn e Maja shareef: Baab Fazal Sadaqat ul Maa)
