"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." (Using translation from Nasāʾī 2382)
كُنَّا مَعَ رَسُولِ اللهِ ﷺ فَمَرَرْنَا بِرَجُلٍ فَقَالُوا يَا نَبِيَّ اللهِ هَذَا لَا يُفْطِرُ مُذْ كَذَا وَكَذَا فَقَالَ «لَا صَامَ وَلَا أَفْطَرَ أَوْ مَا صَامَ وَمَا أَفْطَرَ»
