«وَالسَّمَاءَ بَنَيْنَاهَا بِأَيْدٍ»
And We built the heaven with strength.
The operative meaning of bi-aydin is strength or power. Banaynāhā (“We built it”) can make the everyday association of building with the hand salient, although the intended meaning of bi-aydin is strength or power.
The analysis must not make a physical limb the intended referent. Its point is the meaning of power against the background of the expression for building.
