Aal-E-Imran 3:143

وَلِيُمَحِّصَ ٱللَّهُ ٱلَّذِينَ ءَامَنُوا۟ وَيَمْحَقَ ٱلْكَـٰفِرِينَ

3:141 — And that Allah may purify the believers [through trials] and destroy the disbelievers.

أَمْ حَسِبْتُمْ أَن تَدْخُلُوا۟ ٱلْجَنَّةَ وَلَمَّا يَعْلَمِ ٱللَّهُ ٱلَّذِينَ جَـٰهَدُوا۟ مِنكُمْ وَيَعْلَمَ ٱلصَّـٰبِرِينَ

3:142 — Or do you think that you will enter Paradise while Allah has not yet made evident those of you who fight in His cause and made evident those who are steadfast?

وَمَا مُحَمَّدٌ إِلَّا رَسُولٌ قَدْ خَلَتْ مِن قَبْلِهِ ٱلرُّسُلُ ۚ أَفَإِي۟ن مَّاتَ أَوْ قُتِلَ ٱنقَلَبْتُمْ عَلَىٰٓ أَعْقَـٰبِكُمْ ۚ وَمَن يَنقَلِبْ عَلَىٰ عَقِبَيْهِ فَلَن يَضُرَّ ٱللَّهَ شَيْـًٔا ۗ وَسَيَجْزِى ٱللَّهُ ٱلشَّـٰكِرِينَ

3:144 — Muhammad is not but a messenger. [Other] messengers have passed on before him. So if he was to die or be killed, would you turn back on your heels [to unbelief]? And he who turns back on his heels will never harm Allah at all; but Allah will reward the grateful.

وَمَا كَانَ لِنَفْسٍ أَن تَمُوتَ إِلَّا بِإِذْنِ ٱللَّهِ كِتَـٰبًا مُّؤَجَّلًا ۗ وَمَن يُرِدْ ثَوَابَ ٱلدُّنْيَا نُؤْتِهِۦ مِنْهَا وَمَن يُرِدْ ثَوَابَ ٱلْـَٔاخِرَةِ نُؤْتِهِۦ مِنْهَا ۚ وَسَنَجْزِى ٱلشَّـٰكِرِينَ

3:145 — And it is not [possible] for one to die except by permission of Allah at a decree determined. And whoever desires the reward of this world - We will give him thereof; and whoever desires the reward of the Hereafter - We will give him thereof. And we will reward the grateful.
