How does the word "lamūsiʿūn" (لَمُوسِعُونَ) in the noble verse: "And the heaven We constructed with strength, and indeed, We are its expanders" (وَالسَّمَاءَ بَنَيْنَاهَا بِأَيْدٍ وَإِنَّا لَمُوسِعُونَ) indicate the continuous expansion of the heaven?

Allah Almighty informed us in His Book of the vastness of the heaven when He said: "And the heaven We constructed with strength, and indeed, We are [its] expander" (51:47). The verse indicates that the heaven is in a state of continuous expansion through the word "لَمُوسِعُونَ" (Lamūsi'ūn), which denotes continuity. Modern science has indeed proven this fact.
