Hadith 940:5
Abu al-Mughirah narrated to us, Sa'id ibn 'Abd al-'Aziz narrated to us, Isma'il ibn 'Ubayd Allah narrated to me, from Umm al-Darda', from Abu al-Darda', who said: "We were with the Messenger of Allah, may Allah bless him and grant him peace, on a journey, and one of us would place his hand upon his head due to the intensity of the heat. None of us were fasting, except for the Messenger of Allah, may Allah bless him and grant him peace, and 'Abd Allah ibn Rawahah."
