It is a fact that anyone who desires to attain a worldly wish seeks out the shortest and easiest path to obtain what they desire. For such a person is certain that if they cannot find such a shortcut, they will be delayed in reaching their goal, and if the path is not easy, they know that they may endure much hardship along the way. They also know that the straightest of paths, the one that is the easiest to traverse, is the one without difficulty. In the same way, those who, after purifying their nafs (the lower self), intend to reach Allah, those who desire the blessings of the Hereafter in Paradise, and those who wish to ascend to the malakūt (the spiritual realm of the heavens) and join the ranks of the angels, must certainly seek out the shortest path that will lead them to their goal. (Ihvān, II, 8)
istinbāṭ / mustanbatāt (deduction/inferred rulings): The istinbāṭ (deductive reasoning) of a jurist (faqīh) in matters of rulings means deriving legal judgments from the textual sources (naṣṣ) in accordance with the Sunnah, and thus upholding the sharia (the sacred law). The istinbāṭ of a faqīh in the science of the inner (bāṭin) is to deduce inspirations (khawāṭir) by witnessing rubūbiyya (divine lordship) and conforming to ḥaqīqa (inner reality). (Bayān, 78)
Mustanbatāt (rulings derived through reasoning) are the conclusions reached by those among the verifiers (muḥaqqiqūn) who possess understanding, whether by outward (ẓāhir) or inward (bāṭin) means, in accordance with the Book of Allah, and likewise by following the Messenger of God (peace be upon him) through both outward and inward means, and acting upon these conclusions with both their outward and inward aspects. (Lumaʿ, 147)
