حَدَّثَنَا حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ غَيْلانَ ، نا الْحَسَنُ بْنُ الْجُنَيْدِ ، وَحَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدِ بْنِ إِسْمَاعِيلَ الآدَمِيُّ ، نا مُحَمَّدُ بْنُ عُبَيْدِ اللَّهِ الْمُنَادِي ، قَالا : نا إِسْحَاقُ الأَزْرَقُ ، نا الْقَاسِمُ بْنُ عُثْمَانَ الْبَصْرِيُّ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ : " خَرَجَ عُمَرُ مُتَقَلِّدًا السَّيْفَ ، فَقِيلَ لَهُ : إِنَّ خَتَنَكَ وَأُخْتَكَ قَدْ صَبَوْا ، فَأَتَاهُمَا عُمَرُ وَعِنْدَهُمَا رَجُلٌ مِنَ الْمُهَاجِرِينَ ، يُقَالُ لَهُ : خَبَّابٌ ، وَكَانُوا يَقْرَؤُونَ طه ، فَقَالَ : أَعْطُونِي الْكِتَابَ الَّذِي عِنْدَكُمْ أَقْرَأَهُ ، وَكَانَ عُمَرُ يَقْرَأُ الْكِتَابَ ، فَقَالَتْ لَهُ أُخْتُهُ : إِنَّكَ رِجْسٌ ، وَلا يَمَسُّهُ إِلا الْمُطَهَّرُونَ ، فَقُمْ فَاغْتَسِلْ أَوْ تَوَضَّأْ ، فَقَامَ عُمَرُ فَتَوَضَّأَ ، ثُمَّ أَخَذَ الْكِتَابَ فَقَرَأَ طه " . الْقَاسِمُ بْنُ عُثْمَانَ ، لَيْسَ بِالْقَوِيِّ.
Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: Sayyiduna Umar (may Allah be pleased with him) went out with a sword hanging from his neck, and he was informed: "Your brother-in-law and your sister have become irreligious (meaning they have accepted Islam)." So Sayyiduna Umar (may Allah be pleased with him) came to both of them, and at that time a Muhajir man named Habbab was sitting with them. They were reciting Surah Al-Fatihah, so Sayyiduna Umar (may Allah be pleased with him) said: "This book that you have, give it to me as well so that I may read it." Sayyiduna Umar (may Allah be pleased with him) wanted to read this book, but his sister said to him: "You are impure; only pure people can touch it, so wash yourself or perform ablution." So Sayyiduna Umar (may Allah be pleased with him) got up, performed ablution, then took the writing and read Surah Al-Fatihah. The narrator of this narration, Qasim bin Uthman, is not reliable.
