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.

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
