The Book of Fasting
Mentioning the different reports from Ghaylan bin Jarir about it
أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا مُحَمَّدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ غَيْلاَنَ، أَنَّهُ سَمِعَ عَبْدَ اللَّهِ بْنَ مَعْبَدٍ الزِّمَّانِيَّ، عَنْ أَبِي قَتَادَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم سُئِلَ عَنْ صَوْمِهِ فَغَضِبَ فَقَالَ عُمَرُ رَضِينَا بِاللَّهِ رَبًّا وَبِالإِسْلاَمِ دِينًا وَبِمُحَمَّدٍ رَسُولاً . وَسُئِلَ عَمَّنْ صَامَ الدَّهْرَ فَقَالَ لاَ صَامَ وَلاَ أَفْطَرَ أَوْ مَا صَامَ وَمَا أَفْطَرَ .
It was narrated from Abu Qatadah that: the Messenger of Allah was asked about his fasting and he got angry. 'Umr said: "We are content with Allah as our lord, Islam as our religion and Muhammad as or Prophet." And he was aksed about someone who fasted for the rest of his life and said: "He neither fasted nor broke his fast." 'Ata said: "someone who heard him told me that Ibn 'Umar (said) that the Prophet (ﷺ) said: 'Whoever fasts every day of his life, then he has not fasted."
