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."
Sahih al-Bukhari Book 56, Hadith 205
← Previous Hadith Whenever the Prophet (ﷺ) returned from the Hajj or the `Umra or a Ghazwa, he would say Takbir thrice. Whenever he came upon a mountain path or wasteland, and then he would say, "None has the right to be worshipped but Allah, Alone Who has no partner. All the Kingdom belongs to Him and all the praises are for Him and He is Omnipotent. We are returning with repentance, worshipping, prostrating ourselves and praising our Lord. Allah fulfilled His Promise, granted victory to His slave and He Alone defeated all the clans."

Sahih al-Bukhari Book 56, Hadith 204 Next Hadith → On the day of the battle of the Trench, the Prophet (ﷺ) wanted somebody from amongst the people to volunteer to be a reconnoitre. Az-Zubair volunteered. He demanded the same again and Az-Zubair volunteered again. Then he repeated the same demand (thrice) and AzZubair volunteered once more. The Prophet (ﷺ) then said, " Every prophet has a disciple and my disciple is Az-Zubair."
