Sayyiduna Abu al-Darda' (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "When a man goes out to visit his believing brother, he remains immersed in mercy up to the place where the lower garment is tied (on the waist)." The Prophet (peace and blessings be upon him) said this while placing his hand on his (or his) knee. Then he said: "When he sits with him, mercy covers him." Tabarani recorded it in al-Mu'jam al-Kabir. Its chain contains Mu'awiyah bin Yahya al-Sadafi, who is da'if (weak).
