Sahih Muslim , Book 31, Hadith 19 (In-Book) ⓘ

Abu Sa'id al-Khudri reported: While we were with the Messenger of Allah on a journey, a person came upon his mount and began to stare on the right and on the left, (it was at this moment) that Allah's Messenger said: He who has an extra mount should give that to one who has no mount for him, and he who has surplus of provisions should give them to him who has no provisions, and he made mention of so many kinds of wealth until we were of the opinion that none of us has any right over the surplus.

حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا أَبُو الأَشْهَبِ، عَنْ أَبِي نَضْرَةَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ بَيْنَمَا نَحْنُ فِي سَفَرٍ مَعَ النَّبِيِّ صلى الله عليه وسلم إِذْ جَاءَ رَجُلٌ عَلَى رَاحِلَةٍ لَهُ قَالَ فَجَعَلَ يَصْرِفُ بَصَرَهُ يَمِينًا وَشِمَالاً فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنْ كَانَ مَعَهُ فَضْلُ ظَهْرٍ فَلْيَعُدْ بِهِ عَلَى مَنْ لاَ ظَهْرَ لَهُ وَمَنْ كَانَ لَهُ فَضْلٌ مِنْ زَادٍ فَلْيَعُدْ بِهِ عَلَى مَنْ لاَ زَادَ لَهُ ‏" ‏ ‏.‏ قَالَ فَذَكَرَ مِنْ أَصْنَافِ الْمَالِ مَا ذَكَرَ حَتَّى رَأَيْنَا أَنَّهُ لاَ حَقَّ لأَحَدٍ مِنَّا فِي فَضْلٍ ‏.‏
