Yahya related to me from Malik from Humayd at-Tawil that Anas ibn Malik said, "We once travelled with the Messenger of Allah, may Allah bless him and grant him peace, 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."

Muwatta Malik Book 18, Hadith 25
