وَلَوْ شَآءَ رَبُّكَ لأَمَنَ مَنْ فِي الأَرْضِ كُلُّهُمْ جَميعاً أَفَاَنْتَ تُكْرِهُ النَّاسَ حَتَّي يَكُونُوا مُؤْمِنِينَ

99. “And if your Lord had willed, whoever is on the earth would have believed, all of them, all together. Will thou then compel the people till they become believers?”

Man is free and faith is based upon one’s voluntary choice; it is not to be accepted under compulsion or by imposition. Allah is Omnipotent and Omniscient, employing His power in such a way that it does not run contrary to His Knowledge. And as His omniscience requires mankind to be free, He never compels them to accept faith by force. The Prophet (S) has compassionately insisted that people accept the faith on the basis of voluntary acceptance and not through compulsion.

The verse says:

“And if your Lord had willed, whoever is on the earth would have believed, all of them, all together. Will thou then compel the people till they become believers?”
