Surah Yunus (Jonah), Verse 99

وَلَوْ شَآءَ رَبُّكَ لَاٰمَنَ مَنْ فِی الْاَرْضِ كُلُّهُمْ جَمِیْعًا اَفَاَنْتَ تُكْرِهُ النَّاسَ حَتّٰی یَكُوْنُوْا مُؤْمِنِیْنَ ۟

Wa law shaaa'a Rabbuka la aamana man fil ardi kulluhum jamee'aa; afa anta tukrihun naasa hattaa yakoonoo mu'mineen

“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!”
