[Machine] Indeed, we invade this land (Maghrib) while its inhabitants are pagan, and they have a nearby source of milk and water. Ibn Abbas said, "Tanning is cleansing." Then Ibn Wahlah asked, "Is this your opinion or something you heard?" He replied, "No, it is something I heard from the Messenger of Allah ﷺ ."  

الطبراني:١٢٩٧٩ – حَدَّثَنَا بَكْرُ بْنُ سَهْلٍ الدِّمْيَاطِيُّ ثنا عَبْدُ اللهِ بْنُ يُوسُفَ ثنا بَكْرُ بْنُ مُضَرَ ثنا جَعْفَرُ بْنُ رَبِيعَةَ أَنَّهُ سَمِعَ أَبَا الْخَيْرِ يُخْبِرُ عَنِ ابْنِ وَعْلَةَ أَنَّهُ سَأَلَ ابْنَ عَبَّاسٍ فَقَالَ

إِنَّا نَغْزُو هَذَا الْمَغْرِبَ وَهُمْ أَهْلُ وَثَنٍ وَلَهُمْ قِرِبٌ يَكُونُ فِيهَا اللَّبَنُ وَالْمَاءُ فَقَالَ ابْنُ عَبَّاسٍ «الدِّبَاغُ طَهُورٌ» فَقَالَ ابْنُ وَعْلَةَ عَنْ رَأْيِكَ أَوْ شَيْئًا سَمِعْتَهُ؟ قَالَ «بَلْ شَيْءٌ سَمِعْتُهُ مِنْ رَسُولِ اللهِ ﷺ»
