Silsilah as-Sahihah 442 — Not facing or turning back to Qibla while

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Whoever, while relieving himself, neither faces the Qiblah nor turns his back towards it, one good deed will be written for him and one sin will be erased."
