Abu Musa Ashari reported,

My companions sent me to the Prophet ﷺ to ask him for mounts. He said, "By Allah, I will not provide you with any mounts." I had come to him while he was angry.When I returned to him, he said, "Go to your companions and tell them that Allah," or, "that the Messenger of Allah ﷺ will provide you with mounts."
