He said: "We will certainly strengthen thy arm through thy brother, and invest you both with authority, so they shall not be able to touch you: with Our Sign shall ye triumph,- you two as well as those who follow you." Al-Qasas 28:35 ⧉
Tafsir:
When God appoints somebody as His missionary, He provides him with all that is essential for the performance of the task. Similarly, provision was made for Moses according to his special circumstances. By way of authority for his appointment, he was blessed with the ability to perform certain miracles and he was to be aided by his brother. Moses was endowed with an impressive personality so that Pharaoh’s community may not dare to mishandle him. And it was ordained by God that Moses and his companions should finally be supreme.
