The Desirability of Observing Three Days of Fasting in Every Month
وَعَنِ ابْنِ عَبَّاسٍ، رَضِيَ اللَّهُ عَنْهُمَا، قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ لاَ يُفْطِرُ أَيَّامَ الْبِيضِ فِي حَضَرٍ وَلاَ سَفَرٍ ((رَوَاهُ النسائي بإسناد حَسَن)).
Ibn 'Abbas (May Allah be pleased with them) reported: It was the practice of the Messenger of Allah (ﷺ) to not to omit fast on 'bright days' whether he was staying at a place or on a journey. [An-Nasa'i].
