Divine will and predestination (qadr)

۞ وَلَوْ أَنَّنَا نَزَّلْنَآ إِلَيْهِمُ ٱلْمَلَـٰٓئِكَةَ وَكَلَّمَهُمُ ٱلْمَوْتَىٰ وَحَشَرْنَا عَلَيْهِمْ كُلَّ شَىْءٍ قُبُلًا مَّا كَانُوا۟ لِيُؤْمِنُوٓا۟ إِلَّآ أَن يَشَآءَ ٱللَّهُ وَلَـٰكِنَّ أَكْثَرَهُمْ يَجْهَلُونَ

And even if We had sent down to them the angels [with the message] and the dead spoke to them [of it] and We gathered together every [created] thing in front of them, they would not believe unless Allāh should will. But most of them, [of that], are ignorant.

وَلَوْ أَنَّ قُرْءَانًا سُيِّرَتْ بِهِ ٱلْجِبَالُ أَوْ قُطِّعَتْ بِهِ ٱلْأَرْضُ أَوْ كُلِّمَ بِهِ ٱلْمَوْتَىٰ ۗ بَل لِّلَّهِ ٱلْأَمْرُ جَمِيعًا ۗ أَفَلَمْ يَا۟يْـَٔسِ ٱلَّذِينَ ءَامَنُوٓا۟ أَن لَّوْ يَشَآءُ ٱللَّهُ لَهَدَى ٱلنَّاسَ جَمِيعًا ۗ وَلَا يَزَالُ ٱلَّذِينَ كَفَرُوا۟ تُصِيبُهُم بِمَا صَنَعُوا۟ قَارِعَةٌ أَوْ تَحُلُّ قَرِيبًا مِّن دَارِهِمْ حَتَّىٰ يَأْتِىَ وَعْدُ ٱللَّهِ ۚ إِنَّ ٱللَّهَ لَا يُخْلِفُ ٱلْمِيعَادَ

And if there was any Qur’ān [i.e., recitation] by which the mountains would be removed or the earth would be broken apart or the dead would be made to speak, [it would be this Qur’ān], but to Allāh belongs the affair entirely. Then have those who believed not accepted that had Allāh willed, He would have guided the people, all of them? And those who disbelieve do not cease to be struck, for what they have done, by calamity - or it will descend near their home - until there comes the promise of Allāh. Indeed, Allāh does not fail in [His] promise.

لِمَن شَآءَ مِنكُمْ أَن يَسْتَقِيمَ

For whoever wills among you to take a right course.
