Hubble's Law in the Quran long before Hubble's own discovery

[WinterHold]

The verse says:

Sura 51, The Quran:
( 47 )   And the heaven We constructed with hands, and indeed, We are expanding.

Sura 42, The Quran:
( 1 )   Ha, Meem.
( 2 )   'Ayn, Seen, Qaf.
( 3 )   Thus has He revealed to you, [O Muhammad], and to those before you - Allah, the Exalted in Might, the Wise.
( 4 )   To Him belongs whatever is in the heavens and whatever is in the earth, and He is the Most High, the Most Great.
( 5 )   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.
( 6 )   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.

Things "break" when they are "expanded"?

How did Mohammed know that heaven was expanding?
If we assumed ignorance and lying of the author of the Quran; why would they refer explicitly to such a fact?
Even a nomad Muslim in the desert 1400 years ago, would know that the skies (universe) is expanding. Not just that; actually saying otherwise defies the verse above.
The universe is expanding, by the direct statement of verse 47 of Sura 51 in the Quran, and the implicit referring by verse 5 of Sura 42

Long before Hubble's discovery. 1400 years approximately.

Hubble's law is considered the first observational basis for the expansion of the universe

The verse in Arabic:

والسماء بنيناها بأيد وإنا لموسعون
