Has the story of Moses reached thee?
Behold, thy Lord did call to him in the sacred valley of Tuwa-
"Go thou to Pharaoh, for he had indeed transgressed all bounds:
"And say to him, 'Wouldst thou that thou shouldst be purified (from sin)?-
"'And that I guide thee to thy Lord, so thou shouldst fear Him?'"[Qur'an 79:15-19]

Narrated Ibn Abbas(RA): When Allah's Apostle(PBUH) arrived at Medina, he found the Jews observing the fast on the day of 'Ashura' (10th of Muharram). The Prophet asked them (about it) and they replied, "This is the day when Moses became victorious over pharaoh." The Prophet said (to the Muslims), "We are nearer to Moses than they, so fast on this day."
