Sahih Muslim Book - 31, Hadith - 4517

حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ حَدَّثَنَا أَبُو الأَشْهَبِ عَنْ أَبِى نَضْرَةَ عَنْ أَبِى سَعِيدٍ الْخُدْرِىِّ قَالَ بَيْنَمَا نَحْنُ فِى سَفَرٍ مَعَ النَّبِىِّ -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 فِى فَضْلٍ.

It was narrated that Abu Sa'eed Al-Khudri said: Whilst we were on a journey with the Prophet (s.a.w), a man came to him on a mount of his and started looking to his right and left. The Messenger of Allah (s.a.w) said: "Whoever has a surplus mount, let him give it to one who has no mount, and whoever has surplus provisions, let him give them to one who has no provisions." He mentioned various kinds of wealth, until we thought that none of us had any right to any kind of surplus.
