It is narrated on the authority of 'Abdullah b. 'Amr (Radi Allahu Ta'ala Anhu) that a man asked the Messenger of Allah (Sallal Laahu Ta'ala Alayhi Wa Sallam) which of the merits (is superior) in Islam. He (Sallal Laahu Ta'ala Alayhi Wa Sallam) remarked: That you provide food and extend greetings to one whom you know or do not know.
