We should tread the path of truthfulness and righteousness

O pure soul! Follow thou in the footsteps of the truthful and tread the way of the righteous, so that, through truthfulness, thou mayest come to occupy a Seat of Truth, [Qur'án, 54:55] and, through righteousness, thou mayest attain to abiding honour. If the sum of all sins were to be weighed in the balance, falsehood would, on its own, countervail them; nay, its evils would even outweigh them and its detriment prove greater. It were better for thee that thou shouldst be a blasphemer and tell the truth than that thou shouldst mouth the formulas of faith and yet be a liar. These clear words are addressed as an admonition to the peoples of the world. Render thanks unto God that it is through thee that this counsel hath been addressed to all mankind.
