I heard Abul-Bakhtari At-Taʿi say: Someone who heard ‘Ali ؓ told me that he said: When the Messenger of Allah ﷺ sent me to Yemen, I said: Are you sending me when I am young and I do not know much about judging? The Messenger of Allah ﷺ struck my chest and said: Go, for Allah, may He be glorified and exalted, will make your tongue steadfast and guide your heart.ʿ He said: I never found it difficult to judge between two people. (Using translation from Aḥmad 1145)
سَمِعَ عَلِيًّا ؓ يَقُولُ لَمَّا بَعَثَنِي رَسُولُ اللهِ ﷺ إِلَى الْيَمَنِ فَقُلْتُ يَا رَسُولَ اللهِ تَبْعَثُنِي وَأَنَا رَجُلٌ حَدِيثُ السِّنِّ لَا عَلِمَ لِي بِكَثِيرٍ مِنَ الْقَضَاءِ؟ قَالَ فَضَرَبَ يَدَهُ فِي صَدْرِي وَقَالَ إِنَّ اللهَ سَيُثَبِّتُ لِسَانَكَ وَيَهْدِي قَلْبَكَ فَمَا أَعْيَانِي قَضَاءٌ بَيْنَ اثْنَيْنِ
