It is narrated from Sayyiduna Talq bin Ali (may Allah be pleased with him) that he was present with the Messenger of Allah (peace and blessings be upon him) when a man asked him (peace and blessings be upon him) about a man praying in a single garment, and he (peace and blessings be upon him) said nothing. Then, when the iqamah for the prayer was called, the Messenger of Allah (peace and blessings be upon him) put his two garments together and prayed in them.
