This hadith has been narrated on the authority of Hisham with the same chain of transmitters that Hamza said
I am a person much used to fasting. Should I fast during the journey? (The rest of the hadith is the same.)
Hamza b. 'Amr al-Aslami (Allah be pleased with him) said
Messenger of Allah, I find strength in me for fasting on a journey; is there any sin upon me (in doing it)? Thereupon the Messenger of Allah (ﷺ) said: It is a concession from Allah. He who took advantage of it, it is good for him, and he who preferred to observe fast, there is no sin upon him. Harun (one of the narrators) in his narration said: 'lt is a concession, and he made no mention of" from Allah".

Rawaha.
