Ibrahim Abu Isma`il As-Saksaki:
I heard Abu Burda who accompanied Yazid bin Abi Kabsha on a journey. Yazid used to observe
fasting on journeys. Abu Burda said to him, "I heard Abu Musa several times saying that Allah's
Apostle said, 'When a slave falls ill or travels, then he will get reward similar to that he gets for good
deeds practiced at home when in good health."
