'Ikrimah bin Salamh narrated that :
there were two brothers from among the sons of Mughirah. One of them swore an oath to set a slave free if the other one fixed a piece of wood to his wall. Mujammi' bin Yazid and many men from among the Ansar came and said: “We bear witness that the Messenger of Allah ﷺ said: 'None of you should refuse to let his neighbor fix a piece of wood to his wall.' ” He said: 'O my brother, judgment has been passed in your favor against me, but I have sworn an oath.' So go ahead and fix your wood to my wall.”

حَدَّثَنَا أَبُو بِشْرٍ، بَكْرُ بْنُ خَلَفٍ حَدَّثَنَا أَبُو عَاصِمٍ، عَنِ ابْنِ جُرَيْجٍ، عَنْ عَمْرِو بْنِ دِينَارٍ، أَنَّ هِشَامَ بْنَ يَحْيَى، أَخْبَرَهُ أَنَّ عِكْرِمَةَ بْنَ سَلَمَةَ أَخْبَرَهُ أَنَّ أَخَوَيْنِ مِنْ بَلْمُغِيرَةَ أَعْتَقَ أَحَدُهُمَا أَنْ لاَ يَغْرِزَ خَشَبًا فِي جِدَارِهِ فَأَقْبَلَ مُجَمِّعُ بْنُ يَزِيدَ وَرِجَالٌ كَثِيرٌ مِنَ الأَنْصَارِ فَقَالُوا نَشْهَدُ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " لاَ يَمْنَعْ أَحَدُكُمْ جَارَهُ أَنْ يَغْرِزَ خَشَبَةً فِي جِدَارِهِ " . فَقَالَ يَا أَخِي إِنَّكَ مَقْضِيٌّ لَكَ عَلَىَّ وَقَدْ حَلَفْتُ فَاجْعَلْ أُسْطُوَانًا دُونَ حَائِطِي أَوْ جِدَارِي فَاجْعَلْ عَلَيْهِ خَشَبَكَ .
