Muwatta Imam Malik Book of Fasting, Hadith 23

Yahya related to me from Malik from Humayd at-Tawil that Anas ibn Malik said, "We once travelled with the Messenger of Allah ﷺ in Ramadan, and those who were fasting did not find fault with those who were not, and those who were not fasting did not find fault with those who were."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ حُمَيْدٍ الطَّوِيلِ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّهُ قَالَ سَافَرْنَا مَعَ رَسُولِ اللَّهِ ﷺ فِي رَمَضَانَ فَلَمْ يَعِبِ الصَّائِمُ عَلَى الْمُفْطِرِ وَلاَ الْمُفْطِرُ عَلَى الصَّائِمِ .
