Dalail al-Khayrat - The Waymarks of Benefits
It is said that the author of Dala'il ul-Khayrat,Imam Muhammad al-Jazuli, went on a journey. He found himself in great need of water for making ablutions required before prayers. He came upon a well but could not reach the water far below, as there was no bucket and rope. He became very worried . A young girl saw this and came to his assistance. She spat into the well whereupon the water rose to the top of its own accord. Seeing this miracle, he asked the girl, "And how is that possible?" She replied "I was able to do this due to my invoking excessive blessings upon Prophet Muhammad, upon whom be Allah's blessings and peace." Having thus seen the benefit of invoking blessings upon the Prophet, Imam Jazuli decided to write Dala'il ul-Khayrat. In it, he compiled litanies invoking peace and blessings upon the Prophet. It is by far the most popular and universally-acclaimed collection of prayers upon the Prophet, used throughout the Muslim world and recited individually and in groups, in homes and in mosques, silently and aloud.
