Arabic (Original)
حَدَّثَنَا أَبُو الْيَمَانِ أَخْبَرَنَا شُعَيْبٌ قَالَ قَالَ نَافِعٌ قَالَ عَبْدُ اللَّهِ بْنُ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ لَا يَبِيعُ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلَا يَخْطُبُ بَعْضُكُمْ عَلَى خِطْبَةِ بَعْضٍ.
English Translation
Abu al-Yaman told us, Shu'ayb told us: Nafi' said: Abdullah ibn Umar, may Allah be pleased with them both, said: I heard the Messenger of Allah, peace and blessings be upon him, say: "None of you should undercut another's sale, and none of you should propose marriage over another's proposal."
