Proofs of Allah's Oneness abound in the Creation of the Heavens and Earth
The preceding verses mentioned the reality of the Hereafter and the Judgment Day, and the punishment of those who denied the reality. The present set of verses reaffirm the perfect power of Allah, reminding us about the reality of the Day of Resurrection and allaying the doubt and suspicion of those who deny the reality. It proves the oneness of Allah and reiterates emphatically to believe in the Messenger ﷺ .
بَنَيْنَاهَا بِأَيْدٍ وَإِنَّا لَمُوسِعُونَ (And the sky was built by Us with might, and indeed, We are the One who expands.... Adh-Dhariyat 51:47 ⧉). The word aidin, according to Sayyidna Ibn ` Abbas ؓ ، means strength or power in this context.
