Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Among the believers, the most complete in faith are those who are best in character, who are humble, who love others and are loved by them. And there is no good in a person who neither loves others nor is loved by them."
