"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. "' (Using translation from Nasāʾī 4672)

جَاءَ رَجُلٌ مِنْ بَنِي الصَّعْقِ أَحَدُ بَنِي كِلَابٍ إِلَى رَسُولِ اللهِ ﷺ فَسَأَلَهُ عَنْ عَسْبِ الْفَحْلِ «فَنَهَى عَنْهُ»
