Thus has He revealed to you, [O Muhammad], and to those before you – Allah , the Exalted in Might, the Wise.
To Him belongs whatever is in the heavens and whatever is in the earth, and He is the Most High, the Most Great.
The heavens almost break from above them, and the angels exalt [ Allah ] with praise of their Lord and ask forgiveness for those on earth. Unquestionably, it is Allah who is the Forgiving, the Merciful.
And those who take as allies other than Him – Allah is [yet] Guardian over them; and you, [O Muhammad], are not over them a manager.
Chapter 42 Ash-Shūraâ : Verses 3-6
The Revelation and Allah’s Might
(Likewise Allah, the Almighty, the All-Wise sends revelation to you as to those before you.) means, `just as this Qur’an has been revealed to you, so too the Books and Scriptures were revealed to the Prophets who came before you.’
(Allah, the Almighty) means, in His vengeance
(the All-Wise) means, in all that He says and does. Imam Malik, may Allah have mercy on him, narrated that `A’ishah, may Allah be pleased with her, said, “Al-Harith bin Hisham asked the Messenger of Allah , `O Messenger of Allah, how does the revelation come to you’ The Messenger of Allah said:
(Sometimes it comes to me like the ringing of a bell, which is the most difficult for me; then it goes away, and I understand what was said. And sometimes the angel comes to me in the image of a man, and he speaks to me and I understand what he says.)” `A’ishah, may Allah be pleased with her, said, “I saw him receiving the revelation on a very cold day, and when it departed from him, there were beads of sweat on his forehead.” It was also reported in the Two Sahihs, and the version quoted here is that recorded by Al-Bukhari.
(To Him belongs all that is in the heavens and all that is on the earth,) means, everything is subject to His dominion and control.
(and He is the Most High, the Most Great.) This is like the Ayat:
(the Most Great, the Most High) (13:9), and
(He is the Most High, the Most Great) (22:62). And there are many similar Ayat.
(Nearly the heavens might be rent asunder from above them,) Ibn `Abbas, may Allah be pleased with him, Ad-Dahhak, Qatadah, As-Suddi and Ka`b Al-Ahbar said, “Out of fear of His might.”
(and the angels glorify the praises of their Lord, and ask for forgiveness for those on the earth.) This is like the Ayah:
(Those who bear the Throne and those around it glorify the praises of their Lord, and believe in Him, and ask forgiveness for those who believe (saying): “Our Lord! You comprehend all things in mercy and knowledge,”) (40:7)
(Lo! Verily, Allah is the Oft-Forgiving, the Most Merciful.) This is a reminder, to take heed of this fact.
(And as for those who take as protecting friends others besides Him) This refers to the idolators,
(Allah is Hafiz over them.) meaning, He is Witness to their deeds, recording and enumerating them precisely, and He will requite them for them in full.
(and you are not a trustee over them.) meaning, `you are just a warner, and Allah is the Trustee of all affairs.’
