Arabic (Original)
حَدَّثَنَا يُونُسُ حَدَّثَنِي حَمَّادٌ يَعْنِي ابْنَ زَيْدٍ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنْ عَبْدِ اللَّهِ رَفَعَهُ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا يَبِيعُ الرَّجُلُ عَلَى بَيْعِ أَخِيهِ وَلَا يَخْطُبُ إِلَّا بِإِذْنِهِ أَوْ قَالَ إِلَّا أَنْ يَأْذَنَ لَهُ.
English Translation
Yunus told us, Hammad - that is, Ibn Zayd - told me, from Ayyub, from Nafi', from Abdullah, raising it to the Prophet, peace and blessings be upon him, who said: "A man should not undercut the sale of his brother, nor propose marriage except with his permission" - or he said: "unless he gives him permission."
