Recommended precaution (Arabic: احتياط مستحب, romanized: Ihtiyat Mustahabb) is a fiqh term, prominently used by Shi'a marjas when giving fatwas. Ihtiyat is an action in such a way that includes certain knowledge to original Taklif. This term is considered from two views: the first is Usuli view and the other is juridical perspective (fiqh). In Usuli view, Ihtiyat is concerned with the principle of Ihtiyat while in juridical view, Ihtiyat dealt with Ijtihad, imitation and Qisas.

There are many definitions for recommended precaution (Ihtiyat) in fiqh books and essays. Ihtiyat is observed where the man of jurisprudence does not say anything about fatwa and on the other hand jurists choose the way of imitation freely. Sometimes Ihtiyat is to action of Mokallaf (one who must act religious tasks) in such a way that the one find definite knowledge of original task. Ihtiyat sometimes is along with the repetition of action and sometimes with ^{[clarification needed]} is not along with. There is also a difference between Ihtiyat in fatwa and giving fatwa in recommended precaution. Ihtiyat literally means preservation and keeping. Caution concerned primarily with action but Tavaqqof with creating rules.

There are many divisions in Ihtiyat and its types. Ihtiyat divided in one hand into indispensable, mostahab and needed and in other hand in respect to action, not action and collection of action and not action.

Three groups of verses refer to indispensability of ihtiyat.

(O man), follow not that whereof thou hast no knowledge. Lo! the hearing and the sight and the heart - of each of these it will be asked.
