The mother of Hazrat Ali, Fatima bint Asad had gone to Kaba for worship. When retired from worship, she stood; and at that very moment, the time of the Ali’s birth became matured. Closely was one another chamber, whose wall cracked down, and there quickly became a hole like a window. The mother got into the window. On that moment, Ali was born physically, the form of Divine Light. The wall joined again, but the place on the wall where its split left a crack is visible on every 13th Rajab of lunar year.
