the life of this world and rising of the life of the hereafter, which are among the truths of belief, cause no harm to the certainty of belief. Furthermore, the well-known rule, A possibility that does not arise from any proof or evidence is of no importance is one of the established principles of both the sciences of the principles of religion and the principles of jurisprudence (fiqh).
If you say: “What is the wisdom and purpose in scruples being visited on us, which are thus harmful and an affliction for believers?”
The Answer: On condition they do not lead to excess or overwhelm a person, essentially scruples are the cause of vigilance, lead to seeking the best way, and give rise to seriousness. They banish indifference and repulse carelessness. Therefore, in this realm of examination and arena of competition, the Absolutely Wise One put them in the hand of Satan as a whip of encouragement for us. He strikes it at our heads. If it hurts excessively, one must complain to the All-Wise and Compassionate One, and say: “I seek refuge with God from Satan the Accursed.”
