Hadith 20:

It was narrated that Abdullah ibn Mas’ud (r.a) said: The Messenger of Allah (s.a.w) drew a line for us, then he said: «This is the path of Allah.» Then he drew other lines to its right and left, then he said: «These are other paths - Yazid said: Splitting in different directions - on each of these paths there is a devil calling people to it.» Then he recited: {And, (moreover], this is My path, which is straight, so follow it; and do not follow [other] ways, for you wil be separated from His way}

[al-An'am 6:153].
