(18) باب الْيَمِينِ فِيمَا لاَ يَمْلِكُ، وَفِي الْمَعْصِيَةِ، وَفِي الْغَضَبِ
Narrated Abu Musa:
My companions sent me to the Prophet (ﷺ) to ask him for some mounts. He said, "By Allah! I will not mount you on anything!" When I met him, he was in an angry mood, but when I met him (again), he said, "Tell your companions that Allah or Allah's Messenger (ﷺ) will provide you with mounts."
