Abu Sa'id al-Khudri (Allah be pleased with him) reported:We went out on an expedition with Allah's Messenger (ﷺ) on the 16th of Ramadan. Some of us fasted and some of us broke the fast. But neither the observer of the fast found fault with one who broke it, nor the breaker of the fast found fault with one who observed it.
حَدَّثَنَا هَدَّابُ بْنُ خَالِدٍ، حَدَّثَنَا هَمَّامُ بْنُ يَحْيَى، حَدَّثَنَا قَتَادَةُ، عَنْ أَبِي نَضْرَةَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، - رضى الله عنه - قَالَ غَزَوْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم لِسِتَّ عَشْرَةَ مَضَتْ مِنْ رَمَضَانَ فَمِنَّا مَنْ صَامَ وَمِنَّا مَنْ أَفْطَرَ فَلَمْ يَعِبِ الصَّائِمُ عَلَى الْمُفْطِرِ وَلاَ الْمُفْطِرُ عَلَى الصَّائِمِ .
