[Machine] The Prophet Muhammad ﷺ and Abu Bakr did not appoint a judge, and the first person to practice qada (judicial duties) was Umar. Umar said to him, "Keep the people away from me regarding the dirham and dirhamayn(few silver coins)."
أَنَّ رَسُولَ اللهِ ﷺ وَأَبَا بَكْرٍ ؓ لَمْ يَتَّخِذَا قَاضِيًا وَأَوَّلُ مَنِ اسْتَقْضَى عُمَرُ ؓ قَالَ لَهُ رُدَّ عَنِّي النَّاسَ فِي الدِّرْهَمِ وَالدِّرْهَمَيْنِ
