Jonah
وَلَوْ شَآءَ رَبُّكَ لَـَٔامَنَ مَن فِى ٱلْأَرْضِ كُلُّهُمْ جَمِيعًا ۚ أَفَأَنتَ تُكْرِهُ ٱلنَّاسَ حَتَّىٰ يَكُونُوا۟ مُؤْمِنِينَ
And had your Lord willed, those on earth would have believed - all of them entirely. Then, [O Muhammad], would you compel the people in order that they become believers?
Nearby ayahs help place verse 10:99 in sequence and meaning.
وَلَوْ جَآءَتْهُمْ كُلُّ ءَايَةٍ حَتَّىٰ يَرَوُا۟ ٱلْعَذَابَ ٱلْأَلِيمَ
Even if every sign should come to them, until they see the painful punishment.
فَلَوْلَا كَانَتْ قَرْيَةٌ ءَامَنَتْ فَنَفَعَهَآ إِيمَـٰنُهَآ إِلَّا قَوْمَ يُونُسَ لَمَّآ ءَامَنُوا۟ كَشَفْنَا عَنْهُمْ عَذَابَ ٱلْخِزْىِ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَمَتَّعْنَـٰهُمْ إِلَىٰ حِينٍ
Then has there not been a [single] city that believed so its faith benefited it except the people of Jonah? When they believed, We removed from them the punishment of disgrace in worldly life and gave them enjoyment for a time.
وَمَا كَانَ لِنَفْسٍ أَن تُؤْمِنَ إِلَّا بِإِذْنِ ٱللَّهِ ۚ وَيَجْعَلُ ٱلرِّجْسَ عَلَى ٱلَّذِينَ لَا يَعْقِلُونَ
And it is not for a soul to believe except by permission of Allah, and He will place defilement upon those who will not use reason.
قُلِ ٱنظُرُوا۟ مَاذَا فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۚ وَمَا تُغْنِى ٱلْـَٔايَـٰتُ وَٱلنُّذُرُ عَن قَوْمٍ لَّا يُؤْمِنُونَ
Say, "Observe what is in the heavens and earth." But of no avail will be signs or warners to a people who do not believe
