Anas reported God’s messenger as saying, “When God has a good purpose towards His servant He gives him punishment beforehand in this world, but when He has an evil purpose towards His servant He refrains from dealing with his sin till He takes from him full payment for it on the day of resurrection.” Tirmidhi transmitted it.

وَعَنْ أَنَسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا أَرَادَ اللَّهُ تَعَالَى بِعَبْدِهِ الْخَيْرَ عَجَّلَ لَهُ الْعُقُوبَةَ فِي الدُّنْيَا وَإِذَا أَرَادَ اللَّهُ بِعَبْدِهِ الشَّرَّ أَمْسَكَ عَنْهُ بِذَنْبِهِ حَتَّى يُوَافِيَهُ بِهِ يَوْمَ الْقِيَامَةِ» . رَوَاهُ التِّرْمِذِيّ
