Arabic (Original)
حَدَّثَنَا يَزِيدُ أَخْبَرَنَا هَمَّامٌ عَنْ قَتَادَةَ عَنِ الْحَسَنِ عَنْ أَبِي بَكْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا يَقُولَنَّ أَحَدُكُمْ صُمْتُ رَمَضَانَ كُلَّهُ وَلَا قُمْتُهُ كُلَّهُ قَالَ الْحَسَنُ قَالَ أَبِي و قَالَ يَزِيدُ مَرَّةً قَالَ قَتَادَةُ اللَّهُ أَعْلَمُ أَخَافَ عَلَى أُمَّتِهِ التَّزْكِيَةَ أَوْ لَا بُدَّ مِنْ رَاقِدٍ أَوْ غَافِلٍ.
English Translation
Yazid informed us: Hammam, from Qatada, from al-Hasan, from Abu Bakra, who said: The Messenger of God, peace and blessings be upon him, said: "Let none of you say: 'I fasted the whole of Ramadan and stood in prayer through all of it.'" Al-Hasan said: My father said — and Yazid said once: Qatada said: "God knows best whether he feared self-commendation for his nation, or meant that there must be someone dozing off or heedless."
