Yazid bin Hayan narrates about Sayyiduna Zaid bin Arqam (may Allah be pleased with him): Once we presented ourselves before him, and we requested him, "You have seen goodness, you have been with the Prophet (peace and blessings be upon him). You have performed prayers following the Prophet (peace and blessings be upon him)." He replied, "Yes! The Prophet (peace and blessings be upon him) addressed us in a sermon and said: 'I am leaving among you the Book of Allah; it is the rope of Allah. Whoever follows it will remain on guidance, and whoever abandons it will be on the path of misguidance.'"
