(a) Sayyidah Aishah (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) prayed in a patterned cloak with black borders, then said: "The markings of this cloak kept me distracted. Take it to Abu Jahm and bring me a coarse sheet."
(b) In the narration of Imam al-Zuhri (may Allah have mercy on him), he (peace and blessings be upon him) said: "It kept me distracted from my prayer."
