(So let the Children of Israel go with us, and torment them not; indeed, we have come with a sign from your Lord! And peace will be upon him who follows the guidance!") (20:47)
وَاتْرُكِ الْبَحْرَ رَهْوًا "And leave the sea in the state of stillness; (44:24) " The word rahwan means 'to be still/calm/motionless'. When Prophet Musa (علیہ السلام) and his companions crossed the sea, Musa ill naturally desired for the sea to go back to its original state. So he wanted to strike it with his staff so that it would form a barrier between them and Fir'aun to prevent him from reaching them. But Allah commanded him to leave it as it was, quiet and divided, and gave him the glad tidings that they were a host to be drowned, and he should not fear either being overtaken by Fir'aun or drowning in the sea. When Fir'aun, with his host, will reach the middle of the dry path, Allah will cause the water to flow and they will drown. (Ibn Kathir).
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 20–28
The call for Truth is, in fact, a manifestation of God’s power in the shape of reasoning. In this way, God announces Himself through human beings, while He Himself remains unseen. The divine call, therefore, becomes a trial for its addressees. The truth seekers acknowledge it and bow down before it, while those who are enamoured of appearances consider it unimportant and ignore it. But after rejecting the call to accept the Truth, man cannot avoid facing the consequences. During the lifetime of the Prophet, these ruinous consequences became apparent in this world itself, just as had happened in the case of the Pharaoh of Egypt. Where there was no immediate evidence of such divine retribution, the deniers had to face the consequences of their actions after death.
