It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The most complete of the believers in faith are those who are best in character, who are very gentle and humble, who love others and are loved, and he is not one of us who neither loves anyone nor is loved."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Muhammad bin Uyaynah except Ya'qub bin Abi Abbad."
