Sunan Abi Dawud, Hadith 734 ⓘ
Abu Humaid reported to the same effect. He said: When he (the Prophet) prostrated he kept his thighs wide and did not let his belly touch the thighs. Abu Dawud says that Ibn Mubarak narrated this hadith from ‘Abbas b. Sahl, which he did not remember well. It is thought that he has mentioned ‘Isa b. ‘Abd Allah, ‘Abbas b. Sahl and Abu Humaid al-Sa’idi.
حَدَّثَنَا عَمْرُو بْنُ عُثْمَانَ، حَدَّثَنَا بَقِيَّةُ، حَدَّثَنِي عُتْبَةُ، حَدَّثَنِي عَبْدُ اللَّهِ بْنُ عِيسَى، عَنِ الْعَبَّاسِ بْنِ سَهْلٍ السَّاعِدِيِّ، عَنْ أَبِي حُمَيْدٍ، بِهَذَا الْحَدِيثِ قَالَ وَإِذَا سَجَدَ فَرَّجَ بَيْنَ فَخِذَيْهِ غَيْرَ حَامِلٍ بَطْنَهُ عَلَى شَىْءٍ مِنْ فَخِذَيْهِ . قَالَ أَبُو دَاوُدَ رَوَاهُ ابْنُ الْمُبَارَكِ أَخْبَرَنَا فُلَيْحٌ سَمِعْتُ عَبَّاسَ بْنَ سَهْلٍ يُحَدِّثُ فَلَمْ أَحْفَظْهُ فَحَدَّثَنِيهِ أُرَاهُ ذَكَرَ عِيسَى بْنَ عَبْدِ اللَّهِ أَنَّهُ سَمِعَهُ مِنْ عَبَّاسِ بْنِ سَهْلٍ قَالَ حَضَرْتُ أَبَا حُمَيْدٍ السَّاعِدِيَّ بِهَذَا الْحَدِيثِ .
