The Book of the Believer · Hadith 34 (#Ḥadīth #34)

34 - عن الصباح بن سيابة قال: قلت لأبي عبد الله (ع): ما أصاب المؤمن من بلاء فبذنب؟ قال لا، ولكنْ ليَسمعَ أنينَه وشكواه ودعاءَه الذي يُكتب له بالحسنات وتحُطّ عنه السيئاتُ وتدَّخرُ له يوم القيامة.

34. Al-Sabbah ibn Siyabah narrated: I asked Abu 'Abd Allah , 'The affliction that befalls a believer is it because of a sin?' 'No,' he replied, 'It is so that He (Allah) may hear his wails and complaints and supplications for which good deeds are recorded for him and misdeeds are wiped out from him, and a treasure is amassed for him for the Day of Resurrection.
