It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that Sayyiduna Abu Musa (may Allah be pleased with him) asked the Noble Prophet (peace and blessings be upon him) for a mount, but he found the Prophet (peace and blessings be upon him) busy, and the Prophet (peace and blessings be upon him) said: By Allah! I will not give you mounts. When he was about to leave, the Prophet (peace and blessings be upon him) called him back and gave him a mount. He said: O Messenger of Allah! You had sworn that you would not give me a mount? The Prophet (peace and blessings be upon him) said: Then I swear that I will certainly, certainly give you a mount.
