Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated: A man came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! I love you so much that I keep remembering you; if I did not come and see you, I feel my soul would leave me. And it occurs to me that if I enter Paradise, I will be below you in rank; this weighs heavily on me, and I wish to be with you in the same rank. The Messenger of Allah (peace and blessings be upon him) gave him no reply, so Allah, the Mighty and Majestic, revealed this verse: "And whoever obeys Allah and the Messenger, they will be with those upon whom Allah has bestowed favour" [Al-Nisa: 69] to the end of the verse. Then the Messenger of Allah (peace and blessings be upon him) called him and recited it to him.
