حَدَّثَنَا مُسَدَّدٌ، وَابْنُ أَبِي خَلَفٍ، قَالاَ حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ 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 ‏.‏

Abu Hurairah reported the Holy Prophet(PBUH) 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. Translation Not Available
