مُغِلٌّ
1.
A man cleaving to rancour, malevolence, malice, or spite. (TA.)
2.
An unfaithful man; one who acts unfaithfully. (S, * Mgh, O, * TA.) Hence the saying of Shureyh, لَيْسَ عَلَى المُسْتَعِيرِ
غَيْرِالمُغِلِّ ضَمَانٌ, (S, Mgh, O, TA,) وَلَاعَلَى
المُسْتَوْدَعِ, (TA,) i. e. [There is no guaranteeship to be imposed upon the asker of a loan, except the unfaithful, nor upon him who is asked to take charge of a deposit, meaning], except in the case of him who has been unfaithful in respect of the loan and the deposit: or, as some say, by the مُغِلّ is here meant the
مُسْتَغِلّ [i. e. the person employed to bring the
غَلَّة]: but IAth says that the former is the right explanation. (TA.)
