It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Faith has seventy-some branches; the highest of them is the affirmation of 'La ilaha illa Allah' (there is no deity worthy of worship except Allah), and the lowest of them is removing something harmful from the road."
