عَنْ عِكْرَمَةَ بْنِ سَلَمَةَ بْنِ رَبِيعَةَ أَنَّ أَخَوَيْنِ مِنْ بَنِي الْمُغِيرَةِ أَعْتَقَ أَحَدُهُمَا أَنْ لَا يَغْرِزَ خَشَبًا فِي جِدَارِهِ فَلَقِيَا مُجَمِّعَ بْنَ يَزِيدَ الْأَنْصَارِيَّ رَضِيَ اللَّهُ عَنْهُ وَرِجَالًا كَثِيرًا فَقَالُوا نَشْهَدُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ لَا يَمْنَعُ جَارٌ جَارَهُ أَنْ يَغْرِزَ خَشَبًا فِي جِدَارِهِ فَقَالَ الْحَالِفُ أَيْ أَخِي قَدْ عَلِمْتُ أَنَّكَ مَقْضِيٌّ لَكَ عَلَيَّ وَقَدْ حَلَفْتُ فَاجْعَلْ أُسْطُوَانًا دُونَ جِدَارِي فَفَعَلَ الْآخَرُ فَغَرَزَ فِي الْأُسْطُوَانِ خَشَبَةً فَقَالَ لِي عَمْرٌو فَأَنَا نَظَرْتُ إِلَى ذَلِكَ
It is narrated from ‘Ikrimah bin Salamah that there were two brothers from Banu Mughira. One of them swore an oath to free a slave and said that he would not allow his neighbor to place a beam in his wall. Then, when both of them met Sayyiduna Majma‘ bin Yazid Ansari (may Allah be pleased with him) and several Companions, they said: We testify that the Messenger of Allah (peace and blessings be upon him) said: A neighbor should not prevent his neighbor from placing a beam or the like in his wall. Upon hearing this, the one who had sworn the oath said: O my brother! I have realized that this decision will be against me and in your favor, while I have also sworn an oath. Now, you may build a pillar next to my wall. So he did so, and then placed wood on the pillar. ‘Amr said to me: I had seen this thing.
