Narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him), he says: I was sitting with the Messenger of Allah (peace and blessings be upon him), when a man passed by. A person from the people said: O Messenger of Allah! I love this man. The Prophet (peace and blessings be upon him) asked him: Have you informed him about it? He said: No. The Prophet (peace and blessings be upon him) said: Stand up and inform him. So he stood up towards him and said: O so-and-so! By Allah, indeed I love you for the sake of Allah Almighty. He replied: May the One for whose sake you have loved me, love you in return. In another narration, the Prophet (peace and blessings be upon him) said: Stand up and inform him, so that love may be established between both of you.
