Sayyiduna Abu Huraira (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: "People are like mines of gold and silver (of different kinds); the best of them in the pre-Islamic period are the best of them in Islam, provided they gain understanding of the religion."
