Abu Musa asked the Prophet ﷺ to provide him with mounts, but he came at a time when the Prophet was preoccupied. The Prophet ﷺ said, "By Allah, I will not provide you with mounts."When Abu Musa turned to leave, the Prophet ﷺ called him back and said, "You swore that I would not provide you with mounts."Abu Musa replied, "And I swear that you did not provide us with mounts."So the Prophet ﷺ provided them with mounts.
