Sahih Muslim, 2066 b
sahih

This hadith has been reported on the authority of Ash'ath b. Sulaim with the same chain of transmitters but with a slight change of wording that he made no mention of:

" to fulfil the vows" but substituted these words:" finding of the lost articles".

حَدَّثَنَا أَبُو الرَّبِيعِ الْعَتَكِيُّ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ أَشْعَثَ بْنِ سُلَيْمٍ، بِهَذَا الإِسْنَادِ مِثْلَهُ إِلاَّ قَوْلَهُ وَإِبْرَارِ الْقَسَمِ أَوِ الْمُقْسِمِ ‏.‏ فَإِنَّهُ لَمْ يَذْكُرْ هَذَا الْحَرْفَ فِي الْحَدِيثِ وَجَعَلَ مَكَانَهُ وَإِنْشَادِ الضَّالِّ ‏.‏
