عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا يَسُمِ الرَّجُلُ عَلَى سَوْمِ أَخِيهِ وَلَا يَبِيعْ حَاضِرٌ لِبَادٍ دَعُوا النَّاسَ يَرْزُقُ اللَّهُ بَعْضَهُمْ مِنْ بَعْضٍ وَلَا تَشْتَرِطُ امْرَأَةٌ طَلَاقَ أُخْتِهَا
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: A man should not make a deal over his brother’s deal, nor should a townsman sell the goods of a villager. Leave people in their state; Allah provides sustenance to some through others. And no woman should demand the divorce of her sister.
