Humayd reported,

I went out and remained silent. They said to me, "Repeat it."So I said, "Anas informed me that the companions of the Messenger of Allah ﷺ used to travel, and the one fasting would not criticize the one not fasting, nor would the one not fasting criticize the one fasting."Then I met Ibn Abu Mulayka, and he reported to me from Ayesha رضي الله عنها something similar.

و حدثنا أبو بكر بن أبي شيبة حدثنا أبو خالد الأحمر

عن حميد قال

خرجت فصمت فقالوا لي أعد قال فقلت إن أنسا أخبرني أن أصحاب رسول الله ﷺ كانوا يسافرون فلا يعيب الصائم على المفطر ولا المفطر على الصائم فلقيت ابن أبي مليكة فأخبرني عن عائشة رضي الله عنها بمثله
