It was narrated that 'Umar said:

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

أَخْبَرَنِي هَارُونُ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا الْحَسَنُ بْنُ مُوسَى، قَالَ أَنْبَأَنَا أَبُو هِلاَلٍ، قَالَ حَدَّثَنَا غَيْلاَنُ، - وَهُوَ ابْنُ جَرِيرٍ - قَالَ حَدَّثَنَا عَبْدُ اللَّهِ، - وَهُوَ ابْنُ مَعْبَدٍ الزِّمَّانِيُّ - عَنْ أَبِي قَتَادَةَ، عَنْ عُمَرَ، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ فَمَرَرْنَا بِرَجُلٍ فَقَالُوا يَا نَبِيَّ اللَّهِ هَذَا لاَ يُفْطِرُ مُنْذُ كَذَا وَكَذَا . فَقَالَ " لاَ صَامَ وَلاَ أَفْطَرَ " .
