عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: إِنَّ مِنْ أَحَبِّكُمْ إِلَيَّ وَأَقْرَبِكُمْ مِنِّي مَجْلِسًا يَوْمَ الْقِيَامَةِ أَحَاسِنَكُمْ أَخْلَاقًا
Abdullah ibn Amr reported: The Messenger of Allah, peace and blessings be upon him, said, "The most beloved of you to me and the nearest to me on the Day of Resurrection will be those who have the best character."
