What direction was the Prophet Muhammad (saw) facing when answering the call of nature on Hafsa's rooftop?
 Narrated `Abdullah bin `Umar:                     I went up to the roof of Hafsa's house for some job and I saw Allah's Apostle answering the call of nature facing Sham (Syria, Jordan, Palestine and Lebanon regarded as one country) with his back towards the Qibla. (See Hadith No. 147).
