Indeed, this Quran guides to that which is most correct, and gives glad tidings to the believers, who do good deeds, that they shall have a great reward. (17:9)
This Quran, this miracle that is in your hands, on your tongues, in your hearts. This book that is near, accessible, applicable, keep it close to you.
Allah sent down the Quran, and Allah created us. He knows that this Book is the best for us. So make the Quran your guide, your friend, your refuge, and the solution to your worries.
