ابن ماجہ #519
حَدَّثَنَا أَبُو مُصْعَبٍ الْمَدَنِيُّ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ زَيْدِ بْنِ أَسْلَمَ عَنْ أَبِيهِ عَنْ عَطَائِ بْنِ يَسَارٍ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ أَنَّ النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ سُئِلَ عَنْ الْحِيَاضِ الَّتِي بَيْنَ مَکَّةَ وَالْمَدِينَةِ تَرِدُهَا السِّبَاعُ وَالْکِلَابُ وَالْحُمُرُ وَعَنْ الطَّهَارَةِ مِنْهَا فَقَالَ لَهَا مَا حَمَلَتْ فِي بُطُونِهَا وَلَنَا مَا غَبَرَ طَهُورٌ
. It was narrated from Abu Sa'eed Al-Khudri that the Prophet was asked about the water basins located between Makkah and Al-Madinah, which were visited by wild animals, dogs and donkeys, and about using them for means of purification. He said, "Whatever they (the animals) have carried in their bellies is for them, and whatever is left over is for us, and is pure."
أَبِي سَعِيدٍ الْخُدْرِيِّ، ← عَطَائُ بْنُ يَسَارٍ ← أَبِيهِ ← عَبْدُ الرَّحْمَنِ بْنُ زَيْدِ بْنِ أَسْلَمَ، ← أبو مصعب المدني
