وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَصُومُ الِاثْنَيْنِ وَالْخَمِيس. رَوَاهُ التِّرْمِذِيّ وَالنَّسَائِيّ

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.
