Imam Ali (AS) said, 'No servant from amongst our followers (shiaa) who commits an act that we have forbidden dies without first being afflicted with a severe calamity which expiates his sins, be it with regard to his wealth, his children or his own soul, such that he meets Allah with a clean slate. Moreover, if any of his sins remain even after that, then they are expiated by the pain and difficulty at the time of death.
الإمامُ عليٌّ (عَلَيهِ الّسَلامُ): ما مِنَ الشِّيعةِ عَبدٌ يُقارِفُ أمراً نَهَينا عَنهُ فيَموتُ حتّى يُبتَلى ببَلِيّةٍ تُمَحَّصُ بها ذنوبُهُ ، إمّا في مالٍ ، وإمّا في ولدٍ ، وإمّا في نفسِهِ ، حتّى يَلقَى اللّهَ عزّوجلّ وما لَهُ ذنبٌ ، وإنّه لَيَبقى علَيهِ الشيءُ مِن ذنوبِهِ فَيُشَدَّدُ بهِ علَيهِ عِندَ مَوتِهِ .
