What happened when someone told the people offering Fajr prayer at Quba mosque that Qur'anic literature had been revealed to Prophet Muhammad (saw) and he was ordered to turn towards Ka`ba of Mecca?
 Narrated Ibn `Umar:                     While some people were offering Fajr prayer at Quba mosque, someone came to them and said, "Qur'anic literature" has been revealed to Allah's Apostle tonight, and he has been ordered to face the Ka`ba (of Mecca) so you too, should turn your faces towards it. Their faces were then towards Sham (Jerusalem), so they turned towards the Qibla (i.e. Ka`ba of Mecca).
