It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to establish brotherhood among his Companions by pairing them two by two. Then (because of the separation) the night would become hard and long for one of them until he met his brother, and when he met him he would meet him with the utmost love and kindness and ask: "How did your time pass after me?" As for the people in general, not three days would pass over any of them without his knowing how his brother was.
