Surah 9. Al-Tawba, Ayah 32

Lit., "with their mouths" - an allusion to the "sayings" (i.e., beliefs) mentioned in verse {30}.

Lit., "except (illa) that He bring His light to completion", or "to perfection". The expression "for He has willed" (i.e., contrary to what the erring ones want), is here elliptically implied by means of the particle illa.

 i.e., religion of truth.

With their mouths: there is a twofold meaning: (1) the old-fashioned open oil lamps were extinguished by blowing with the mouth; the Unbelievers would like to blow out Allah's Light as it is a cause of offence to them; (2) false teachers and preachers distort the Message of Allah by the false words of their mouth. Their wish is to put out the light of Truth for they are people of darkness; but Allah will perfect His Light, i.e., make it shine all the brighter in the eyes of men. His Light in itself is ever perfect, but it will penetrate the hearts of men more and more, and so become more and more perfect for them.
