Sunan an-Nasai
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ مُحَمَّدِ بْنِ يَحْيَى بْنِ حَبَّانَ، عَنْ عَمِّهِ، وَاسِعِ بْنِ حَبَّانَ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، قَالَ لَقَدِ ارْتَقَيْتُ عَلَى ظَهْرِ بَيْتِنَا فَرَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَلَى لَبِنَتَيْنِ مُسْتَقْبِلَ بَيْتِ الْمَقْدِسِ لِحَاجَتِهِ .
It was narrated that 'Abdullah bin 'Umar said: "I climbed on the roof of our house and saw the Messenger of Allah (ﷺ) on two bricks, facing toward Bait Al-Maqdis (jerusalem), relieving himself."
