Allah(swt), does whatever he wills

 قَالَ اللّهُ إِنِّي مُنَزِّلُهَا عَلَيْكُمْ فَمَن يَكْفُرْ بَعْدُ مِنكُمْ فَإِنِّي أُعَذِّبُهُ عَذَابًا لاَّ أُعَذِّبُهُ أَحَدًا مِّنَ الْعَالَمِينَ 5:115

(Fathe Muhammad Jalandari)
خدا نے فرمايا ميں تم پر ضرور خوان نازل فرماؤں گا ليکن جو اس کے بعد تم ميں سے کفر کرے گا اسے ايسا عذاب دوں گا کہ اہل عالم ميں کسي کو ايسا عذاب نہ دوں گا5:115

(Muhammad Assad)
 5:115 God answered: "Verily, I [always] do send it down unto you: and so, if any of you should henceforth deny [this] truth, on him, behold, will I inflict suffering the like of which I have never [yet] inflicted upon anyone in the world!"5:115

(Yousaf Ali)
 5:115 Allah said: "I will send it down unto you: But if any of you after that resisteth faith, I will punish him with a penalty such as I have not inflicted on any one among all the peoples."5:115
