Ан-Наср 110:2

Verse [ 110:2] وَرَ‌أَيْتَ النَّاسَ يَدْخُلُونَ فِي دِينِ اللَّهِ أَفْوَاجًا (And you see people entering Allah's [ approved ] religion in multitudes,) Before the conquest of Makkah there were many people who were almost convinced of the verity of the Holy Prophet Muhammad ﷺ and Islam, but there were several factors that were obstructing them to embrace the religion. Some people were afraid of the Quraishite opposition, or they were hesitant for some other reason. The Conquest of Makkah removed those obstacles, and people entered the fold of Islam in throngs. Seven hundred people from Yemen embraced the religion, and joined the Holy Prophet ﷺ . On the way, they recited the call to prayer [ adhan ] and recited the Qur'an. In this way, the populace of Arabia embraced the religion of Islam and entered into its fold in droves.
