Hadith 5:99
Abu Huraira reported God’s messenger as saying, “Men’s deeds are presented [to God] on Mondays and Thursdays, and I like mine to be presented when I am fasting.” Tirmidhi transmitted it.
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «تُعْرَضُ الْأَعْمَالُ يَوْمَ الِاثْنَيْنِ وَالْخَمِيسِ فَأُحِبُّ أَنْ يُعْرَضَ عَمَلِي وَأَنَا صَائِمٌ» . رَوَاهُ التِّرْمِذِيُّ
