A summary of the concepts held by the Ahl al-Sunnah. The heart of the believer serves as a deterrent against committing forbidden acts. The faithful heart is filled with the restraint of faith. It is this that holds one back and prevents one from engaging in prohibited deeds. This is more beneficial and effective than all the slogans that warn against various evils. For example: Corruption hinders development and wastes resources. Or "No to drugs." And "Smoking is harmful to health." There is no objection to mentioning such phrases that clarify the worldly harms of these things. However, it is more important to first stimulate the restraint of faith in the believer's heart by explaining the religious harms. Such as the weakening of one's love for Allah, the Almighty and Exalted. And the weakening of one's reverence for Him and submission to Him. A summary of the concepts held by the Ahl al-Sunnah.
