Sahih Muslim | Book 15 | Hadith Number 4050

Narrated by Abu Musa al-Ash'ari
Abu Musa al-Ash'ari reported: We came to Allah's Messenger (may peace be upon him) requesting him to provide us with riding camels. He (the Holy Prophet) said: There is nothing with me with which I should equip you. By Allah, I would not provide you with (riding camels). Then Allah's Messenger (may peace be upon him) sent to us three camels with spotted bumps. We said: We came to Allah's Messenger (may peace be upon him) asking him to equip us with riding animals. He took an oath that he could not equip us. We came to him and informed him. He said: By Allah, I do not take an oath, but when I find the other thing better than that, I do that which is better.
