Sunan Abi Dawud, Hadith 3376 ⓘ

Narrated Ali ibn AbuTalib: A time is certainly coming to mankind when people will bite each other and a rich man will hold fast, what he has in his possession (i.e. his property), though he was not commanded for that. Allah, Most High, said: "And do not forget liberality between yourselves." The men who are forced will contract sale while the Prophet forbade forced contract, one which involves some uncertainty, and the sale of fruit before it is ripe.

حَدَّثَنَا مُحَمَّدُ بْنُ عِيسَى، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا صَالِحُ أَبُو عَامِرٍ، - قَالَ أَبُو دَاوُدَ كَذَا قَالَ مُحَمَّدٌ - حَدَّثَنَا شَيْخٌ، مِنْ بَنِي تَمِيمٍ قَالَ خَطَبَنَا عَلِيُّ بْنُ أَبِي طَالِبٍ - أَوْ قَالَ قَالَ عَلِيٌّ قَالَ ابْنُ عِيسَى هَكَذَا حَدَّثَنَا هُشَيْمٌ، - قَالَ سَيَأْتِي عَلَى النَّاسِ زَمَانٌ عَضُوضٌ يَعَضُّ الْمُوسِرُ عَلَى مَا فِي يَدَيْهِ وَلَمْ يُؤْمَرْ بِذَلِكَ قَالَ اللَّهُ تَعَالَى ‏{‏ وَلاَ تَنْسَوُا الْفَضْلَ بَيْنَكُمْ ‏}‏ وَيُبَايَعُ الْمُضْطَرُّونَ وَقَدْ نَهَى النَّبِيُّ صلى الله عليه وسلم عَنْ بَيْعِ الْمُضْطَرِّ وَبَيْعِ الْغَرَرِ وَبَيْعِ الثَّمَرَةِ قَبْلَ أَنْ تُدْرِكَ ‏.‏
