The observation of consequences is complementary to the objectives of sharia (Islamic Law). Some provisions of Islamic law depends on this principle. For that, the preacher needs this principle in his field of advocacy. Because sometimes, He may think that his actions and his decisions are correct and it is bringing the benefit. While on the other hand, he may stop some actions as he thinks that it is illegal having harmfulness, but it is by looking deeply at the consequences, he may come out with a different judgment by either approving or withholding the decision. Therefore, it is necessary to practice this principle "observe the consequences of the individual behavior" in order to keepthe advocacy in an effective shape.
