حَدَّثَنَا مُحَمَّدُ بْنُ حُمَيْدٍ الرَّازِيُّ، حَدَّثَنَا مُحَمَّدُ بْنُ الْمُعَلَّى، حَدَّثَنَا زِيَادُ بْنُ خَيْثَمَةَ، عَنْ أَبِي دَاوُدَ، عَنْ عَبْدِ اللَّهِ بْنِ سَخْبَرَةَ، عَنْ سَخْبَرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " مَنْ طَلَبَ الْعِلْمَ كَانَ كَفَّارَةً لِمَا مَضَى " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ ضَعِيفُ الإِسْنَادِ . أَبُو دَاوُدَ يُضَعَّفُ وَلاَ نَعْرِفُ لِعَبْدِ اللَّهِ بْنِ سَخْبَرَةَ كَبِيِرَ شَيْءٍ وَلاَ لأَبِيهِ وَاسْمُ أَبِي دَاوُدَ نُفَيْعٌ الأَعْمَى تَكَلَّمَ فِيهِ قَتَادَةُ وَغَيْرُ وَاحِدٍ مِنْ أَهْلِ الْعِلْمِ .
Unreviewed translation. All hadiths in this collection are available in five languages. Titles and introductions may remain in Arabic.
Sakhbarah reported that the Prophet said: ‘Seeking knowledge is an expiation for what came before.’ Abu ‘Isa said: ‘The chain of this hadith is weak. Abu Dawud is considered weak, and we know little about ‘Abdullah ibn Sakhbarah or his father. Abu Dawud’s name was Nufay‘ al-A‘ma; Qatadah and more than one scholar criticized him.’
Notes and open questions — unreviewed
The source explicitly grades the chain weak and names weaknesses among its transmitters; the English wording alone would omit that reliability context.
