[Machine] The Prophet ﷺ received a letter from a man. He said to Abdullah ibn Arqam, "Answer it for me." So he wrote down his response and then read it to him. The Prophet ﷺ said, "You have done well and done good. O Allah, grant him success." When Umar became the leader, he would consult him.
أَتَى النَّبِيَّ ﷺ كِتَابُ رَجُلٍ فَقَالَ لِعَبْدِ اللهِ بْنِ الْأَرْقَمِ أَجِبْ عَنِّي فَكَتَبَ جَوَابَهُ ثُمَّ قَرَأَهُ عَلَيْهِ فَقَالَ أَصَبْتَ وَأَحْسَنْتَ اللهُمَّ وَفِّقْهُ فَلَمَّا وَلِيَ عُمَرُ ؓ كَانَ يُشَاوِرُهُ
