Asim bin Umar narrates: Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) went to visit Muqanna’ (the one with a head covering) who was ill. Sayyiduna Jabir (may Allah be pleased with him) said: I will not leave you until you get cupped, because I heard the Prophet Muhammad (peace and blessings be upon him) say: There is healing in it.
