(78) باب صَوْمِ عَشْرَةِ أَيَّامٍ مِنَ الشَّهْرِ وَاخْتِلاَفِ أَلْفَاظِ النَّاقِلِينَ لِخَبَرِ عَبْدِ اللَّهِ بْنِ عَمْرٍو فِيهِ
It was narrated that 'Abdullah bin 'Amr said:
"The Messenger of Allah said to me" and he quoted the same Hadith. '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."
