(And (remember) when We delivered you from Fir`awn's (Pharaoh) people, who were afflicting you with a horrible torment,) meaning, `I - Allah - saved you from them and delivered you from their hands in the company of Musa, after they subjected you to horrible torture.' This favor came after the cursed Pharaoh had a dream in which he saw a fire emerge from Bayt Al-Maqdis (Jerusalem), and then the fire entered the houses of the Coptics in Egypt, with the exception of the Children of Israel. Its purport was that his kingship would be toppled by a man among the Children of Israel. It was also said that some of Pharaoh's entourage said that the Children of Israel were expecting a man among them to arise who would establish a state for them. We will mention the Hadith on this subject when we explain Surat Ta Ha (20), Allah willing. After the dream, Pharaoh ordered that every newborn male among the Children of Israel be killed and that the girls be left alone. He also commanded that the Children of Israel be given tasks of hard labor and assigned the most humiliating jobs.
Verse 50 refers to certain things which had happened in the days of Sayyidna Musa (علیہ السلام) (Moses). He, in his capacity as a messenger of Allah, continued efforts for a long time to make the Pharaoh and his people see Truth, but when they persisted in their denial, Allah commanded him to take the Israelites along with him and leave Egypt surreptitiously. On their way, they came across a sea while the Pharaoh was behind him with his army in hot pursuit. Allah commanded the sea to split, and make way for Sayyidna Musa (علیہ السلام) and his people. So, they went over smoothly. But when the Pharaoh and his army followed them into the sea, it gathered the water back so that the Pharaoh and his men were drowned then and there.
A doctrinal point
Verse 50 speaks of the splitting of the sea, and clearly proves that miracles do occur at the hands of prophets, which some Westernized Muslims have been trying to deny. (Bayn al-Quran (
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 46–51
As the Israelites were considered representatives of revealed religion in the Arab world, people used to ask them about the Arab Prophet. Pretending innocence, they would put forward such points as would turn people away from the Prophet and his mission. They used to preach to people, exhorting them to follow the truth and live their lives according to it; in practice, however, they failed to accept the truth when their turn came to do so. When a positive response to the call of God means relinquishing positions of high honour and prestige, then those who have gained religious rank through worldly elevation find it extremely difficult to follow this course. For the truly devout, however, these considerations are not a hindrance. The fulfillment that others find in worldly pleasures, true believers find in remembering God, in spending for His cause, in obeying His commandments and being steadfast in treading His path. They know full well that it is God’s punishment that is to be feared, not worldly loss.
