أَخْبَرَنَا مُحَمَّدُ بْنُ يُوسُفَ ، عَنْ سُفْيَانَ ، عَنْ زَيْدِ بْنِ أَسْلَمَ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ وَعْلَةَ ، قَالَ : سَأَلْتُ ابْنَ عَبَّاسٍ عَنْ الْأَسْقِيَةِ، فَقَالَ : مَا أَدْرِي مَا أَقُولُ لَكَ، غَيْرَ أَنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ :" أَيُّمَا إِهَابٍ دُبِغَ فَقَدْ طَهُرَ "
