Thabit bin Aslam Banani (may Allah have mercy on him) says: I was sitting in the mosque with Abdur Rahman bin Abu Laila (may Allah have mercy on him), when a stout man came and said: "O Abu Isa (Abdur Rahman)!" He replied: "Yes." He said: "Relate what you have heard regarding the fara’." So he said: "I heard from my father, who said: I was sitting with the Messenger of Allah (peace and blessings be upon him) when a man came and said: O Messenger of Allah! Can I pray in the fara’?" The Prophet (peace and blessings be upon him) said: "Then what is the benefit of dyeing it?" When he left, I (Thabit) said: "Who was that man?" Abdur Rahman said: "That was Suwaid bin Ghaflah (may Allah be pleased with him)."
