It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him): It was said: O Messenger of Allah, what was the beginning of your matter? He said: "The supplication of my father Ibrahim (peace be upon him), the glad tidings of Isa bin Maryam (peace be upon him), and my mother saw that a light came out of her by which the palaces of al-Sham were illuminated."
