It was narrated that Anas bin Malik said: "A man from Banu As-Sa'q, one of Banu Kilab, came to the Messenger of Allah and asked him about charging stud fees for a stallion. He forbade him to do that, but he said: 'We give payment for that. "'
أَخْبَرَنَا عِصْمَةُ بْنُ الْفَضْلِ، قَالَ حَدَّثَنَا يَحْيَى بْنُ آدَمَ، عَنْ إِبْرَاهِيمَ بْنِ حُمَيْدٍ الرُّؤَاسِيِّ، قَالَ حَدَّثَنَا هِشَامُ بْنُ عُرْوَةَ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ بْنِ الْحَارِثِ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ جَاءَ رَجُلٌ مِنْ بَنِي الصَّعْقِ أَحَدِ بَنِي كِلاَبٍ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَسَأَلَهُ عَنْ عَسْبِ الْفَحْلِ فَنَهَاهُ عَنْ ذَلِكَ فَقَالَ إِنَّا نُكْرَمُ عَلَى ذَلِكَ .
