عَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَ أَبُو طَلْحَةَ يُكْثِرُ الصَّوْمَ عَلَى عَهْدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَلَمَّا مَاتَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ لَا يُفْطِرُ إِلَّا فِي سَفَرٍ أَوْ مَرَضٍ
It is narrated from Sayyiduna Anas (may Allah be pleased with him) that Sayyiduna Abu Talha (may Allah be pleased with him) used to fast frequently during the time of the Messenger of Allah (peace and blessings be upon him). But when the Messenger of Allah (peace and blessings be upon him) passed away, after that he would only miss a fast due to travel or illness.
