It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "I am holding you by your waists (to keep you) from the Fire. I say: Beware of Hell! Beware of the limits (hudud)! Then when I die, I will be your forerunner (at the Pond), and your appointed meeting place will be at the Pond; whoever comes to it will succeed. And some people will come and be taken towards the left, so I will say: O my Lord, my Ummah! And it will be said: You do not know what innovations they introduced after you; they turned back on their heels."
