[Machine] Two men went on a journey and the time for prayer arrived, but they did not have any water with them. So they performed dry ablution on a clean surface and prayed. Then they found water at the time of prayer, so one of them repeated the ablution and prayer, but the other did not. They both went to the Messenger of Allah and informed him about this. He said to the one who did not repeat the ablution and prayer: "You have followed the Sunnah and your prayer is accepted." He said to the one who repeated the ablution and prayer: "You will be rewarded twice." This narration was reported by others from Abdullah bin Nafi', from Layth, from Umair bin Abi Najiyyah, from Bakr bin Sawadah, from Ata' bin Yasar, from the Prophet Muhammad ﷺ , with a connected chain of narrators.

This narration was also reported by Abu Abdullah Al-Haafiz, from Abu Bakr bin Ishaq, from Ahmad bin Ibrahim, from Yahya bin Bakir, from Layth, from Umarah bin Abi Najiyyah. In my book, I mentioned it as Umair bin Abi Najiyyah, and the correct opinion is that it is Umarah bin Abi Najiyyah.

This narration was also reported by Abu Ali Al-Rudhbari, from Abu Bakr bin Dasa, from Abu Dawud, from Al-Qa'nabi, from Ibn Lah'iyah, from Bakr bin Sawadah, from Abu Abdullah, the freed slave of Isma'il bin Ubaid, from Ata' bin Yasar, regarding two companions of the Prophet ﷺ with the same meaning.
