"We were with the Messenger of Allah and we passed by a man. They said: 'O Prophet of Allah, this man has not broken his fast for such and such a time.' He said: 'He has neither fasted nor broken his fast."' 'Ata said: "someone who heard him told me that Ibn 'Umar (said) that the Prophet said: 'Whoever fasts every day of his life, then he has not fasted."  

كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ فَمَرَرْنَا بِرَجُلٍ فَقَالُوا يَا نَبِيَّ اللَّهِ هَذَا لاَ يُفْطِرُ مُنْذُ كَذَا وَكَذَا فَقَالَ لاَ صَامَ وَلاَ أَفْطَرَ  

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 said: 'Whoever fasts every day of his life, then he has not fasted."  

أَنَّ رَسُولَ اللَّهِ ﷺ 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
