ابن ماجہ · Hadith 322

‘Abdullâh bin ‘Umar said: “People say: ‘When you sit to relieve yourself, do not face the Qibith.’ But one day I climbed up onto the roof of our house, and I saw the Messenger of Allah P.B.U.H sitting on two bricks (to relieve himself), facing the direction of Baitul-Maqdis (Jerusalem).” This is a Hadith narrated by Yarid bin Hânin. (Sahih)
