Ibn al-Mubarak reported: Umar ibn al-Khattab, may Allah be pleased with him, said, “Do not let yourselves be impressed by the roar of a man. Rather, if he fulfills the trust and restrains himself from harming the honor of people, he will truly be a man.”

عن ابن المبارك قال عمر بن الخطاب رضي الله عنه لا يُعْجِبَنَّكُمْ مِنَ الرَّجُلِ طَنْطَنَتُهُ وَلَكِنَّهُ مَنْ أَدَّى الأمَانَةَ وَكَفَّ عَنْ أَعْرَاضِ النَّاسِ فَهُوَ الرَّجُلُ
