"My father told me that he heard the Messenger of Allah say, when mention was made in his presence of a man who fasted for the rest of his life: '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."  

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ وَذُكِرَ عِنْدَهُ رَجُلٌ يَصُومُ الدَّهْرَ قَالَ لاَ صَامَ وَلاَ أَفْطَرَ  

[Machine] "He (referring to the Prophet) was asked, or the Prophet of Allah was asked, about a man who fasts continuously. He (the Prophet) replied, 'He neither fasts nor breaks his fast.'"  

أَنَّهُ سَأَلَ النَّبِيَّ ﷺ أَوْ سُئِلَ نَبِيُّ اللهِ ﷺ عَنْ رَجُلٍيَصُومُ الدَّهْرَ فَقَالَ لَا صَامَ وَلَا أَفْطَرَ
