And We took the Children of Israel across the sea, and Firaun (Pharaoh) and his hosts followed them in oppression and enmity, till when the drowning overtook him, he said, I believe that La ilaha jib (Huwa) (none has the right to be worshipped but) He (Allah), in Whom the Children of IsrAel believe, and I am one of the Muslims (those who submit to Allahs Will). (V.10:90)

Narrated Ibn `Abbas

When the Prophet (ﷺ) arrived at Medina, the Jews were observing the fast on 'Ashura' (10th of Muharram) and they said, "This is the day when Moses became victorious over Pharaoh," On that, the Prophet (ﷺ) said to his companions, "You (Muslims) have more right to celebrate Moses' victory than they have, so observe the fast on this day."
