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.
English Translation of Hadith
Hazrat Abu Musa (May Allah be pleased with him) reported: Messenger of Allah 
[SAWW] (PBUH) said, “The relationship of the believer with another believer is like (the bricks of) a building, each strengthens the other.” He [SAWW](PBUH) illustrated this by interlacing the fingers of both his hands.
[Al-Bukhari Volume 3, Book 43, Number Hadith 626)
Lesson : as mentioned above in Surah Al-Qasas Ayat 35. Allah said: Musa “We will strengthen your arm through your brother, and give you both power, This Hadith enjoins unity in the Muslim community, each member of which is like a brick, which, when they are all combined, lend strength to each other. Similarly, Muslims are like hands and arms, which physically joined together, are bound to cooperate with one another.
