A hadith like this has been transmitted by Ibn 'Umar (Allah be pleased with both of them), but he did not make mention of (the words):" During the month of Ramadan."
وَحَدَّثَنَا عَبْدُ الْوَارِثِ بْنُ عَبْدِ الصَّمَدِ، حَدَّثَنِي أَبِي، عَنْ جَدِّي، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، - رضى الله عنهما - عَنِ النَّبِيِّ صلى الله عليه وسلم بِمِثْلِهِ وَلَمْ يَقُلْ فِي رَمَضَانَ .
