حَدَّثَنَا أَبُو بَکْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ وَعَبْدُ اللَّهِ بْنُ نُمَيْرٍ قَالَا حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عُمَرَ عَنْ نَافِعٍ عَنْ ابْنِ عُمَرَ أَنَّ النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا کَفَّرَ الرَّجُلُ أَخَاهُ فَقَدْ بَائَ بِهَا أَحَدُهُمَا
صحیح مسلم · Hadith 215
It is reported on the authority of Abu Huraira that the Messenger of Allah (may peace and blessings of Allah be upon him) made observations like them embodied in the hadith narrated by Yahya b. Muhammad on the authority of 'Ala', and added to it: even if he observed fast and prayed and asserted that he was a Muslim.
