Yahya related to me from Malik from Rabia ibn Abi Abd ar-Rahman from more than one source that the Messenger of Allah ﷺ assigned the mines of al Qabaliyya, which is in the direction of al-Fur, to Bilal ibn Harith al-Mazini, and nothing has been taken from them up to this day except zakat.
أَنَّ رَسُولَ اللَّهِ ﷺ قَطَعَ لِبِلاَلِ بْنِ الْحَارِثِ الْمُزَنِيِّ مَعَادِنَ الْقَبَلِيَّةِ وَهِيَ مِنْ نَاحِيَةِ الْفُرْعِ فَتِلْكَ الْمَعَادِنُ لاَ يُؤْخَذُ مِنْهَا إِلَى الْيَوْمِ إِلاَّ الزَّكَاةُ
Rabi'ah reported on the authority of more than one person saying: The Messenger of Allah ﷺ assigned as a fief to Bilal ibn al-Harith al-Muzani the mines of al-Qabaliyyah which is in the neighbourhood of al-Fur', and only zakat is levied on those mines up to the present day.

أَنَّ النَّبِيَّ ﷺ أَقْطَعَ بِلَالَ بْنَ الْحَارِثِ الْمُزَنِيَّ مَعَادِنَ الْقَبَلِيَّةِ وَهِيَ مِنْ نَاحِيَةِ الْفُرْعِ فَتِلْكَ الْمَعَادِنُ لَا يُؤْخَذُ مِنْهَا إِلَّا الزَّكَاةُ إِلَى الْيَوْمِ
