“I once asked abu ‘Abd Allah (a.s.), about performing optional Salah (prayer) on the back of camel or stumper. He (the Imam) said, ‘Yes, you can do so as your face is.’ I then asked, ‘Am I required to face al-Qiblah (al-Ka‘bah) when saying Takbir (Allah is great beyond description)? He (the Imam) said, ‘No, you are not required but say Takbir (Allah is great beyond description) as your face is and that is how the Messenger of Allah of had done.’”
