Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
"And indeed We revealed to Musa (Moses) (saying): 'Travel by night with 'Ibâdi (My slaves) and strike a dry path for them in the sea, fearing neither to be overtaken [by Fir'aūn (Pharaoh)], nor being afraid (of drowning in the sea).' Then Fir'aūn (Pharaoh) pursued them with his hosts, but the sea-water completely overwhelmed them and covered them up. And Fir'aun (Pharaoh) led his people astray, and he did not guide them." (V.20:77-79)
Narrated Ibn `Abbas:
When Allah's Messenger (ﷺ) arrived at Medina, he found the Jews observing the fast on the day of 'Ashura' (10th of Muharram). The Prophet (ﷺ) asked them (about it) and they replied, "This is the day when Moses became victorious over Pharaoh." The Prophet (ﷺ) said (to the Muslims), "We are nearer to Moses than they, so fast on this day."
