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 ".
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."
