Shu’bah bin Taw’am narrates: Sayyiduna Qais bin ‘Asim (may Allah be pleased with him) asked the Noble Prophet (peace and blessings be upon him) about making an ally (according to the custom of the pre-Islamic era): so the Noble Prophet (peace and blessings be upon him) said: There is no making of an ally (in this manner) in Islam.
