Sunan an-Nasa'i
It was narrated that 'Abdullah bin 'Amr said: "The Messenger of Allah (ﷺ) said to me" and he quoted the same Hadith. '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."
أَخْبَرَنَا عَلِيُّ بْنُ الْحُسَيْنِ، قَالَ حَدَّثَنَا أُمَيَّةُ، عَنْ شُعْبَةَ، عَنْ حَبِيبٍ، قَالَ حَدَّثَنِي أَبُو الْعَبَّاسِ، - وَكَانَ رَجُلاً مِنْ أَهْلِ الشَّامِ وَكَانَ شَاعِرًا وَكَانَ صَدُوقًا - عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم وَسَاقَ الْحَدِيثَ .
