أَخْبَرَنِي إِبْرَاهِيمُ بْنُ الْحَسَنِ، قَالَ حَدَّثَنَا الْحَجَّاجُ بْنُ مُحَمَّدٍ، قَالَ قَالَ ابْنُ جُرَيْجٍ سَمِعْتُ نَافِعًا، يُحَدِّثُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يَقُولُ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ يَبِيعَ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلاَ يَخْطُبُ الرَّجُلُ عَلَى خِطْبَةِ الرَّجُلِ حَتَّى يَتْرُكَ الْخَاطِبُ قَبْلَهُ أَوْ يَأْذَنَ لَهُ الْخَاطِبُ .
Ibrahim ibn al-Hasan informed me; he said: al-Hajjaj ibn Muhammad narrated to us; he said: Ibn Jurayj said: I heard Nafi narrating that Abd Allah ibn Umar used to say: The Messenger of Allah (peace and blessings of Allah be upon him) forbade some of you from outbidding others in a sale, and a man from making a proposal over another man’s proposal, until the earlier suitor withdraws or gives him permission.
Translation notes
This wording states two conditions for a competing proposal to proceed: the earlier suitor withdraws or permits it.
