Abu Hurairah reported the Holy Prophet ﷺ as saying:

When one of you asks permission for inserting a wooden peg in his wall, he should not prevent him. So they (the people) lowered down their heads. Then he (Abu Hurairah) said: What is the matter ? I am seeing you are neglecting (to hear this tradition), I shall spread it among you.

Abu Dawud said:This is the tradition of Ibn Abi Khalaf is more perfect.

حَدَّثَنَا مُسَدَّدٌ، وَابْنُ أَبِي خَلَفٍ، قَالاَ حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " إِذَا اسْتَأْذَنَ أَحَدُكُمْ أَخَاهُ أَنْ يَغْرِزَ خَشَبَةً فِي جِدَارِهِ فَلاَ يَمْنَعْهُ " . فَنَكَسُوا فَقَالَ مَا لِي أَرَاكُمْ قَدْ أَعْرَضْتُمْ لأُلْقِيَنَّهَا بَيْنَ أَكْتَافِكُمْ . قَالَ أَبُو دَاوُدَ وَهَذَا حَدِيثُ ابْنِ أَبِي خَلَفٍ وَهُوَ أَتَمُّ .
