ISTIHSAN استحسان
Lit. “Approving.” A term used in the exegesis of the Qur’an and of the Hadis. It implies the rejection of Qiyas [QIYAS], and the admission of the law of expediency.
For example, it is a law of Islam that everything that is washed must be squeezed like a cloth; but, as it is impossible to squeeze a vessel, it is evident that it must be cleansed without squeezing. (Nuru ‘l-Anwar, p. 206.)
