It is narrated from Sayyiduna Sahl bin Hunaif (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said to him: "You are my envoy and messenger to the people of Makkah, so say to them that the Messenger of Allah (peace and blessings be upon him) sends you greetings of peace and commands you that when you go out (to relieve yourselves), do not face towards the Qiblah nor turn your back to it."
