The Prophet looked for a shirt for him. It was found that the shirt of 'Abdullah bin Ubai would do, so the Prophet let him wear it. That was the reason why the Prophet took off and gave his own shirt to 'Abdullah. (The narrator adds, "He had done the Prophet some favor for which the Prophet liked to reward him.")“. 2012-yil 13-oktyabrda asl nusxadan arxivlangan. Qaraldi: 2015-yil 20-sentyabr.
