It is narrated from Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "After me there will be trials, in which this will happen and that will happen." We said: If we live to see that time, will we be destroyed? He (peace and blessings be upon him) said: "For my Companions, being killed is sufficient."
