أَخْبَرَنَا يَزِيدُ بْنُ هَارُونَ ، أَخْبَرَنَا مُحَمَّدُ بْنُ إِسْحَاق ، عَنْ مُحَمَّدِ بْنِ جَعْفَرِ بْنِ الزُّبَيْرِ ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ ، عَنْ أَبِيهِ رَضِيَ اللهُ عَنْهُ، قَالَ : سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ يُسْأَلُ عَنْ الْمَاءِ يَكُونُ بِالْفَلَاةِ مِنْ الْأَرْضِ وَمَا يَنُوبُهُ مِنْ الدَّوَابِّ وَالسِّبَاعِ؟، فَقَالَ :" إِذَا بَلَغَ الْمَاءُ قُلَّتَيْنِ لَمْ يُنَجِّسْهُ شَيْءٌ "
