It was narrated from Anas that there was a group of the Companions of the Prophet, one of whom said: "I will not marry women." Another said: "I will not eat meat." Another said: "I will not sleep on a bed." Another said: "I will fast and not break my fast." News of that reached the Messenger of Allah and he praised Allah then said: "What is the matter with people who say such and such? But I pray and I sleep, I fast and I break my fast, and I marry women. Whoever turns away from my Sunnah is not of me." (Using translation from Nasāʾī 3217)
أَنَّ نَفَرًا مِنْ أَصْحَابِ النَّبِيِّ ﷺ سَأَلُوا أَزْوَاجَ النَّبِيِّ ﷺ عَنْ سَرِيرَتِهِ فَقَالَ بَعْضُهُمْ لَا أَتَزَوَّجُ النِّسَاءَ وَقَالَ بَعْضُهُمْ لَا آكُلُ اللَّحْمَ وَقَالَ بَعْضُهُمْ لَا أَنَامُ عَلَى فِرَاشٍ وَقَالَ بَعْضُهُمْ أَصُومُ وَلَا أُفْطِرُ فَبَلَغَ ذَلِكَ النَّبِيَّ ﷺ فَقَامَ وَحَمِدَ اللهَ وَأَثْنَى عَلَيْهِ ثُمَّ قَالَ مَا بَالُ أَقْوَامٍ قَالُوا كَذَا وَكَذَا لَكِنِّي أُصَلِّي وَأَنَامُ وَأَصُومُ وَأُفْطِرُ وَأَتَزَوَّجُ النِّسَاءَ فَمَنْ رَغِبَ عَنْ سُنَّتِي فَلَيْسَ مِنِّي لَفْظُ حَدِيثِ أَبِي عُثْمَانَ وَحَدِيثِ الرُّوذْبَارِيِّ مُخْتَصَرٌ لَيْسَ فِيهِ حِكَايَةُ أَقْوَالِهِمْ
