Narrated AbuBakrah:

The Prophet ﷺ said: One of you should not say: I fasted the whole of Ramadan, and I prayed during the night in the whole of Ramadan. I do not know whether he disliked the purification; or he (the narrator) said: He must have slept a little and taken rest.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنِ الْمُهَلَّبِ بْنِ أَبِي حَبِيبَةَ، حَدَّثَنَا الْحَسَنُ، عَنْ أَبِي بَكْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " لاَ يَقُولَنَّ أَحَدُكُمْ إِنِّي صُمْتُ رَمَضَانَ كُلَّهُ وَ قُمْتُهُ كُلَّهُ " . فَلاَ أَدْرِي أَكَرِهَ التَّزْكِيَةَ أَوْ قَالَ لاَ بُدَّ مِنْ نَوْمَةٍ أَوْ رَقْدَةٍ .
