Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrated: I asked the Messenger of Allah (peace and blessings be upon him): Which people are the best? He (peace and blessings be upon him) said: "My generation, then those who come after them, then those who come after them. Then there will come people, the testimony of one of whom will precede his oath, and his oath will precede his testimony."
