[2:49] And when We delivered you from the folk of Pharaoh who were visiting you with evil chastisement, slaughtering your sons, and sparing your women; and for you therein was a tremendous trial from your Lord.
Whoever has patience in God with the affliction of His enemies, God will compensate him with the companionship of His friends and He will grant him His beautiful gift. The Children of Israel were patient in enduring injury from Pharaoh and his people, so He appointed their prophets from among them and made them kings. He gave them what He had not given anyone in all the worlds.
And for you therein was a tremendous trial from your Lord: It is said [it was] a great blessing and a severe trial. In truth, what was from God was externally a trial but it was really, for the one who recognized it, a blessing and a kindness.
