Sayyiduna Abu Ruhm (may Allah be pleased with him) narrates: We were travelling, and beside me was someone who would come close up against me at night; I did not recognise him. It was the Prophet (peace and blessings be upon him). He asked: "Who is this?" I said: "Abu Ruhm." The Prophet (peace and blessings be upon him) said: "What has become of those men who are tall, curly-haired and wheat-complexioned, who belong to Banu Ghifar? Is any one of them with us on this march?" I said: "No." The Prophet (peace and blessings be upon him) said: "What has become of those people who are wheat-complexioned, short, and snub-nosed, who belong to the tribe of Aslam? Is any of them marching with us?" I said: "No." The Prophet (peace and blessings be upon him) said: "What has become of those people who are red-complexioned and whose beards are sparse? Is any one man of them marching with us?" I said: "No." The Prophet (peace and blessings be upon him) said: "It is not so grievous to me that anyone of my household stays behind from me as it is grievous (to me) that anyone of the people of Quraysh, the Ansar, Aslam or Ghifar stays behind. When one of them has stayed behind, what prevents him from lending one of his camels to someone for temporary use? Then he would receive a reward like that of the one who goes out."
Al-Bazzar recorded it with two chains. Its chain contains the nephew of Sayyiduna Abu Ruhm (may Allah be pleased with him), whom I do not know; the rest of the narrators of one of the two chains are thiqat (trustworthy).
