Yunus (Jonas) 10:99

<h2>It is not Part of Allah's Decree to compel Belief</h2><p>Allah said: </p><div class="arabic uthmani">وَلَوْ شَآءَ رَبُّكَ</div><p>(And had your Lord willed) meaning `O Muhammad, if it had been the will of your Lord, He would make all the people of the earth believe in what you have brought to them. But Allah has wisdom in what He does.' Similarly, Allah said: </p><div class="arabic uthmani">وَلَوْ شَآءَ رَبُّكَ لَجَعَلَ النَّاسَ أُمَّةً وَاحِدَةً وَلاَ يَزَالُونَ مُخْتَلِفِينَ </div><div class="arabic uthmani">إِلاَّ مَن رَّحِمَ رَبُّكَ وَلِذلِكَ خَلَقَهُمْ وَتَمَّتْ كَلِمَةُ رَبِّكَ لاّمْلاّنَّ جَهَنَّمَ مِنَ الْجِنَّةِ وَالنَّاسِ أَجْمَعِينَ </div><p>(And if your Lord had so willed, He could surely have made mankind one Ummah, but they will not cease to disagree.

(11:118-119) He also said, </p><div class="arabic uthmani">أَفَلَمْ يَاْيْـَسِ الَّذِينَ ءَامَنُواْ أَن لَّوْ يَشَآءُ اللَّهُ لَهَدَى النَّاسَ جَمِيعًا</div><p>(Have not then those who believed yet known that had Allah willed, He could have guided all mankind) (13:31) Therefore, Allah said: </p><div class="arabic uthmani">أَفَأَنتَ تُكْرِهُ النَّاسَ</div><p>(So, will you then compel mankind) and force …

And if thy Lord willed, all who are in the earth would have believed together. Wouldst thou (Muhammad) compel men until they are 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 had your Lord willed, those on earth would have believed, all of them together. So, will you (O Muhammad SAW) then compel mankind, until they become believers.

Had your Lord willed, everyone on earth would have believed. Will you compel people to become believers?
