Abu Saeed al-Khudri said: Two persons set out on a journey. Meanwhile the time of prayer came and they had no water. They performed tayammum with clean earth and prayed. Later on they found water within the time of the prayer. One of them repeated the prayer and ablution but the other did not repeat. Then they came to the Messenger of Allah صلی اللہ علیہ وسلم and related the matter to him. Addressing himself to the one who did not repeat, he said: You followed the sunnah (model behavior of the Prophet) and your (first) prayer was enough for you. He said to the one who performed ablution and repeated: For you there is the double reward. Abu Dawud said: Besides Ibn Nafi this is transmitted by al-Laith from Umairah bin Abi Najiyyah from Bakr bin Sawadah on the authority of Ata bin Yasar from the Prophet صلی اللہ علیہ وسلم. Abu Dawud said: The mention of (the name of the Companion) Abu Saeed in this tradition is not guarded. This is a mural tradition (i. e. the Successor Ata bin Yasar directly narrates it from the Prophet, leaving the name of the Companion in the chain. )
