English Translation of Al-Quran
[28].Surah Al-Qasas [The Narration]
Ayat 35. Allah said: Musa “We will strengthen your arm through your brother, and give you both power, so they shall not be able to harm you, with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), you two as well as those who follow you will be the victors.”
Tafseer of Surah Al-Qasas (The Narration) Ayat 35. 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.” To touch you: to approach you anywhere near, in the wonders and Signs that you will show them under the divine authority with which you are invested. The potency of Allah’s Light is such that its divine rays reach the humblest of those who seek after Him. The Prophets can certainly work wonders, but their sincere followers in Faith can do so also in their own spheres. Wonders may appeal to people, but they are not the highest Signs of Allah’s workings, and they are around us every day in our lives.
