Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that a man came to the Prophet (peace and blessings be upon him) and asked: "Which people are the best?" The Prophet (peace and blessings be upon him) replied: "The best (or most virtuous) among the people is the one who strives in the way of Allah with his wealth and his life. (After him is) the believer who worships Allah in a mountain pass and does not cause any harm to the people."
