Surah 31. Luqman
Ayah 22 - 24
22وَمَن يُسْلِمْ وَجْهَهُۥٓ إِلَى ٱللَّهِ وَهُوَ مُحْسِنٌ فَقَدِ ٱسْتَمْسَكَ بِٱلْعُرْوَةِ ٱلْوُثْقَىٰ ۗ وَإِلَى ٱللَّهِ عَـٰقِبَةُ ٱلْأُمُورِ
23وَمَن كَفَرَ فَلَا يَحْزُنكَ كُفْرُهُۥٓ ۚ إِلَيْنَا مَرْجِعُهُمْ فَنُنَبِّئُهُم بِمَا عَمِلُوٓا۟ ۚ إِنَّ ٱللَّهَ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ
24نُمَتِّعُهُمْ قَلِيلًا ثُمَّ نَضْطَرُّهُمْ إِلَىٰ عَذَابٍ غَلِيظٍ
[22-24] Whoever surrenders himself to Allah,40 and is a doer of good,41 he has indeed taken hold of a reliable support42 and the ultimate disposal of all affairs is in the hand of Allah. As for the one who disbelieves, let not his disbelief grieve you.43 To Us they have to return; then We shall tell them what they had been doing. Most surely Allah knows the hidden secrets of the breasts. We are allowing them to enjoy themselves for a while in the world; then We shall drag them to a severe torment in a helpless condition.
40"Whoever........Allah": Who submits himself wholly to the service of Allah, entrusts all his affairs to Him and makes His Guidance the law of his entire life.
41That is, practically also he should adopt the attitude of an obedient servant of Allah.
42That is, He will neither have the apprehension that he will be misguided, nor the fear that he will meet an evil end after having served Allah.
43This means to say, "O Prophet, the one who refuses to listen to you, thinks that by rejecting Islam and insisting on unbelief he has harmed you, but in fact he has not harmed you but harmed only himself. If he does not listen to you, you need not bother yourself about him at all. "
