Those who were compromising the Prophet (saws) will have children who will convert to Islam as indicated in the next Surah “Al-Nassr” which gives good tiding that the people will enter into the religion of Allah (swt) in multitudes, among them will be the  children and grand children of those disbelievers, subsequently, the disbelief community will no longer be in the face of the belief community because this is the only religion.

Farwah bin Nawfal quoted that the Prophet (saws) said to Nawfal (his father):

“Recite (the Surah) ‘Say, O you disbelievers!’ and then go to sleep at its end, for it is a declaration of freedom from polytheism.”[1]
