وَلَوْ شَاء رَبُّكَ لآمَنَ مَن فِي الأَرْضِ كُلُّهُمْ جَمِيعًا أَفَأَنتَ تُكْرِهُ النَّاسَ حَتَّى يَكُونُواْ مُؤْمِنِينَ
[10:99]
And if your Lord had pleased, surely all those who are in the earth would have believed, all of them; will you then force men till they become believers?
If it had been thy Lord's will, they would all have believed,- all who are on earth! wilt thou then compel mankind, against their will, to believe!
And if thy Lord willed, all who are in the earth would have believed together. Wouldst thou (Muhammad) compel men until they are believers?
