Never plead ignorance, about the obvious existence of Allah, that evolution is a deceit and Allah creates everything, about the miraculous features of living beings surrounding you, the everything you possess is a favour from Allah, of the fact that you won't stay long in this world, of the fact that death is inevitable, of the fact that the Qur'an is the just book and that you will be judged according to it, about the voice of your conscience, of that fact that Allah commands man to conduct himself correctly, of the fact that disbelief, is the source of all wickedness, about the existence of the hereafter and the day of judgement, of the fact that the hell is a place of torment for all eternity, that matter is only an image, that time is a variable perception and that everything is predestined.
