'I fasted Ramadan' or 'I prayed Qiyam throughout the whole month."' I do not know whether he dislike self-praise or he said: "Inevitably there will be heedlessness and sleep." (Da 'if) (Using translation from Nasāʾī 2109)
عَنِ النَّبِيِّ ﷺ قَالَ لَا يَقُولَنَّ أَحَدُكُمْ إِنِّي قُمْتُ رَمَضَانَ كُلَّهُ وَصُمْتُهُ قَالَ فَلَا أَدْرِي أَكَرِهَ التَّزْكِيَةَ أَمْ لَا بُدَّ مِنْ غَفْلَةٍ أَوْ رَقْدَةٍ
'I fasted Ramadan' or 'I prayed Qiyam throughout the whole month."' I do not know whether he dislike self-praise or he said: "Inevitably there will be heedlessness and sleep." (Da 'if)
عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَقُولَنَّ أَحَدُكُمْ صُمْتُ رَمَضَانَ وَلاَ قُمْتُهُ كُلَّهُ وَلاَ أَدْرِي كَرِهَ التَّزْكِيَةَ أَوْ قَالَ لاَ بُدَّ مِنْ غَفْلَةٍ وَرَقْدَةٍ اللَّفْظُ لِعُبَيْدِ اللَّهِ
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.
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
[Machine] The Messenger of Allah ﷺ said, "None of you should say, 'I have observed the entirety of Ramadan.'" Qatadah said, "Allah knows best. I fear that it may be considered boasting against His Ummah or it may be said, 'There must be a slumbering or an ignorant person.'"
أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَقُولَنَّ أَحَدُكُمْ إِنِّي قُمْتُ رَمَضَانَ كُلَّهُ قَالَ قَتَادَةُ فَاللهُ أَعْلَمُ أَخَشِيَ التَّزْكِيَةَ عَلَى أُمَّتِهِ أَوْ يَقُولُ لَا بُدَّ مِنْ رَاقِدٍ أَوْ غَافِلٍ
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. (Using translation from Abū Dāʾūd 2415)
عَنِ النَّبِيِّ ﷺ قَالَ «لَا يَقُولَنَّ أَحَدُكُمْ إِنِّي صُمْتُ رَمَضَانَ كُلَّهُ وَقُمْتُهُ» قَالَ فَلَا أَدْرِي أَكَرِهَ التَّزْكِيَةَ أَمْ قَالَ «لَا بُدَّ مِنْ رَقْدَةٍ أَوْ غَفَلَةٍ»

عَنِ النَّبِيِّ ﷺ قَالَ «لَا يَقُولَنَّ أَحَدُكُمْ صُمْتُ رَمَضَانَ وَلَا قُمْتُهُ كُلَّهُ» فَلَا أَدْرِي كِرَهَ التَّزْكِيَةَ أَوْ قَالَ لَا بُدَّ مِنْ غَفْلَةٍ وَرَقْدَةٍ اللَّفْظُ لِعُبَيْدِ اللهِ
