We used to travel with the Prophet ﷺ during Ramadan. Some of us fasted and others did not, and neither the one fasting found fault with the one not fasting, nor did the one not fasting find fault with the one fasting.
حدثنا علي بن عاصم أخبرنا سعيد بن إياس عن أبي نضرة
كنا نسافر مع النبي ﷺ في رمضان فمنا الصائم ومنا المفطر فلا يعيب الصائم على المفطر ولا المفطر على الصائم
Its isnad is sahih. Saeed bin Iyas is Jareeri, who appears often. The hadith was narrated by Bukhari 4/186, no. 1947, in the Book of Fasting, "The companions of the Prophet ﷺ did not criticize one another over fasting or breaking the fast," and by Nasai 4/188, no. 2310, similarly.
