What did Prophet Muhammad (saw) say regarding the reward for a slave who falls ill or travels?
 Narrated 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."
