Sunan Abi Dawud, Hadith 328 ⓘ
Aban said: Qatadah was asked about tayammum during a journey. He said: A traditionist reported to me from al-Sha'bi from 'Abd al-Rahman b. Abza on the authority of 'Ammar b. Yasir who reported the Messenger of Allah as saying: (He should wipe) up to the elbows.
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبَانُ، قَالَ سُئِلَ قَتَادَةُ عَنِ التَّيَمُّمِ، فِي السَّفَرِ فَقَالَ حَدَّثَنِي مُحَدِّثٌ، عَنِ الشَّعْبِيِّ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى، عَنْ عَمَّارِ بْنِ يَاسِرٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِلَى الْمِرْفَقَيْنِ " .
