[Machine] The Prophet ﷺ received a letter from a man, so he said to Abdullah ibn Arqam, "Answer me." He wrote his response and then read it to him. He said, "You are right, and you did well. O Allah, grant him success." When Umar became the Caliph, he used to consult him.
أَتَى النَّبِيَّ ﷺ كِتَابُ رَجُلٍ فَقَالَ لِعَبْدِ اللَّهِ بْنِ الْأَرْقَمِ «أَجِبْ عَنِّي» فَكَتَبَ جَوَابَهُ ثُمَّ قَرَأَهُ عَلَيْهِ فَقَالَ «أَصَبْتَ وَأَحْسَنْتَ اللَّهُمَّ وَفِّقْهُ» فَلَمَّا وَلِيَ عُمَرُ كَانَ يُشَاوِرُهُ
