Hamza bin Amr reported,

Someone said, "Messenger of Allah, I find I have the strength to fast while traveling. Is there any blame on me for doing so?"The Messenger of Allah ﷺ replied, "It is a concession from Allah. Whoever takes it has done well, and whoever wishes to fast, there is no blame on him."

Sahih

عن حمزة بن عمرو الأسلمي، قال

يا رسول الله أجد بي قوة على الصيام في السفر، فهل علي جناح؟ فقال رسول الله ﷺ: هي رخصة من الله، فمن أخذ بها فحسن، ومن أحب أن يصوم فلا جناح عليه.
