Sliman Ben Ibrahim,
The Life of Mohammad, the Prophet of Allah
“ Every day, after the morning prayer, we go to the Hira, a burning plain, covered with scattered black pebbles and which stretches out south-west of the town. There, our hands shading our eyes from the dazzling sun, we gaze as far as our sight permits, hoping to catch sight of Allah's Apostle. We turn not back in the direction of our dwellings until high noon, doubly defeated by the blaze of the perpendicular rays of the sun and their reverberation on white sand and calcined stones. ”
