Al-Matalib al-'Aliyah 2570 — Good character

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) asked (Sayyidah Umm Abd (may Allah be pleased with her)): "O Umm Abd, do you know who is the most excellent of the believers in faith?" She said that Allah and His Messenger know best. He (peace and blessings be upon him) said: "Those who are the best in their character, who are very gentle, humble and courteous. And no servant can attain the true essence of faith until he loves for other people what he loves for himself, and until his neighbour is safe and secure from his mischief, harm and calamities."
The chain of this hadith contains the narrator Kawthar bin Hakim, who is matruk (abandoned) and very weak, on account of which this report is weak in its chain; however, its various parts and meanings are established by other sahih hadith and supporting reports.
