Hazrat Abdur Rahman bin Uthman says that I stood behind Maqam Ibrahim to offer prayer, and I wished that on that night no one else would stand at that place except me. Meanwhile, a man tried to get my attention from behind. I did not pay attention, so he tried again. When I turned around, I saw that it was Hazrat Uthman bin Affan. I stepped back, and he stood there and completed the prayer after reciting the entire Holy Qur'an in a single rak'ah.
