A 9: Undoubtedly, some scholars may not take this matter seriously for some engagements, weakness of knowledge, or illness that makes them unable to observe this, or for other reasons and they may not be truthful in that. For example, some may think that they are not qualified for that, or see that others have fulfilled this duty on their behalf and so there is no need for them, in addition to other excuses. However, my advice to a knowledge seeker is not to slacken in Da`wah, claiming that there are others carrying out that important task. Nevertheless, he should call to Allah (Exalted be He) according to his capability and knowledge, but not to engage himself in what he can not bear. He should also call to Allah (Exalted be He) according to his knowledge, endeavor to cite the evidence, and never say anything about Allah (Exalted be He) without knowledge. He should not also despise himself so long as he has knowledge and good understanding of religion.
