Mukhtasar Bukhari

Narrated Abdullah bin Umar (may Allah be pleased with them): I often remembered the saying of the poet and looked at the face (blessed) of the Prophet (peace be upon him) when he would supplicate for rain (Istisqa). He (peace be upon him) would not descend (from the pulpit) before streams would begin to flow everywhere. (The poet's saying is:) "Fair is his complexion, the protector of orphans and widows. People seek rain by virtue of his countenance." And these are the words of Abu Talib.
