Allah puts his servants through in this world to cleanse them before their final accounting

The Messenger of Allah ﷺ said: “When Allah intends good for His servant, He hastens punishment for him in this world; and when He intends evil for His servant, He withholds it from him for his sin until he is made to fully meet it on the Day of Resurrection.”

With this chain of narration, from the Prophet ﷺ he said: “Indeed, the greatness of the reward comes with the greatness of the trial. And indeed, when Allah loves a people, He tests them: whoever is satisfied will have satisfaction, and whoever is displeased will have displeasure.”

قَالَ رَسُولُ اللَّهِ ﷺ: «إِذَا أَرَادَ اللَّهُ بِعَبْدِهِ الْخَيْرَ عَجَّلَ لَهُ الْعُقُوبَةَ فِي الدُّنْيَا، وَإِذَا أَرَادَ اللَّهُ بِعَبْدِهِ الشَّرَّ أَمْسَكَ عَنْهُ بِذَنْبِهِ حَتَّى يُوَفَّى بِهِ يَوْمَ الْقِيَامَةِ»،

وَبِهَذَا الإِسْنَادِ عَنِ النَّبِيِّ ﷺ قَالَ: «إِنَّ عِظَمَ الْجَزَاءِ مَعَ عِظَمِ الْبَلاَءِ، وَإِنَّ اللَّهَ إِذَا أَحَبَّ قَوْمًا ابْتَلاَهُمْ، فَمَنْ رَضِيَ فَلَهُ الرِّضَا، وَمَنْ سَخِطَ فَلَهُ السَّخَطُ».
