29 Preface يا أَيُّهَا الَّذينَ آمَنوا إِن تَتَّقُوا اللَّهَ يَجعَل لَكُم فُرقانًا وَيُكَفِّر عَنكُم سَيِّئَاتِكُم وَيَغفِر لَكُم ۗ وَاللَّهُ ذُو الفَضلِ العَظيمِAli Quli QaraiO you who have faith! If you are wary of Allah, He shall appoint a criterion1 for you, and absolve you of your misdeeds, and forgive you, for Allah is dispenser of a great grace. That is, a knowledge which will enable you to distinguish between truth and falsehood.
