They want to extinguish the light of Allah with their mouths, but (61:8)

Almuntakhab Fi Tafsir Alquran Alkarim

They wish they could, with all the feeling in their minds directed toward falsifying the truth, quench the very light of Allah by word of mouth, (that is by propagating false rumours and uttering error against Him). But Allah shall continue to send His illumination -the Quran- which proceeds from Him until the souls have been lit by the divine truth and enlightenment has prevailed albeit this is hateful to those who refuse to acknowledge the truth

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(61:8) They seek to blow out Allah's Light with their mouths, but Allah has decreed that He shall perfect His Light, much as the disbelievers may dislike it. *12

They want to extinguish the light of Allah with their mouths, but meaning

*12) One should bear in mind that these verses were sent down in A.H. 3 after the Battle of Uhud, when Islam was confined only to the city of Madinah, the Muslims were only a few thousands in number, and entire Arabia was bent upon wiping out this religion. The defeat that the Muslims had suffered at Uhud, had sullied their image of power and the tribes of the surrounding areas had been emboldened. Under such conditions it was said: "No one will succeed in blowing out this Light of Allah, but it will shine forth in all fullness and spread throughout the world." This was a clear prediction which literally came true. Who could know apart from Allah at that time what was the future of Islam? Human eyes could only sec that it was a flickering candle and violent winds were blowing to put it out for ever.

یہ لوگ اپنے منہ کی پھونکوں سے اللہ کے نور کو بجھانا چاہتے ہیں، اور اللہ کا فیصلہ یہ ہے کہ وہ اپنے نور کو پوا پھیلا کر رہے گا خواہ کافروں کو یہ کتنا ہی ناگوار ہو
