I ascended the roof of the house and saw the Apostle of Allaah ( sal Allaahu alayhi wa sallam) sitting on two bricks facing Jerusalem (Bait al-Maqdis) for relieving himself.
Sunan Abi Dawud Book 1, Hadith 12
← Previous Hadith I saw Ibn Umar make his camel kneel down facing the qiblah, then he sat down urinating in its direction. So I said: AbuAbdurRahman, has this not been forbidden? He replied: Why not, that was forbidden only in open country; but when there is something between you and the qiblah that conceals you , then there is no harm.

Sunan Abi Dawud Book 1, Hadith 11 Next Hadith → The Prophet of Allah (ﷺ) forbade us to face the qiblah at the time of making water. Then I saw him facing it (qiblah) urinating or easing himself one year before his death.
