Sahih al-Bukhari, Book 83, Hadith 55 (In-Book) ⓘ
Narrated Abu Musa: My companions sent me to the Prophet 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 will provide you with mounts."
حَدَّثَنِي مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ بُرَيْدٍ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ أَرْسَلَنِي أَصْحَابِي إِلَى النَّبِيِّ صلى الله عليه وسلم أَسْأَلُهُ الْحُمْلاَنَ فَقَالَ " وَاللَّهِ لاَ أَحْمِلُكُمْ عَلَى شَىْءٍ ". وَوَافَقْتُهُ وَهْوَ غَضْبَانُ فَلَمَّا أَتَيْتُهُ قَالَ " انْطَلِقْ إِلَى أَصْحَابِكَ فَقُلْ إِنَّ اللَّهَ ـ أَوْ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم ـ يَحْمِلُكُمْ ".
