Musnad Ahmad 26:886

Aswad ibn Amir narrated to us, Abu Bakr narrated to us, from Asim, from Abu Wa’il, from Abdullah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) drew a line with his hand, then said: "This is the straight path of Allah." He said: Then he drew lines to its right and its left, then said: "These are the paths; there is not a single path among them except that upon it is a devil calling to it." Then he recited: "And indeed, this is My path, which is straight, so follow it; and do not follow [other] ways" [Al-An'am: 153].
