مُطْمَيءِنٌّ
2.
And A man (S) still, in a state of rest or ease, quiet, or calm; (S, Mgh, K;) as also
طَمْنٌ, (K,) but this is a word unused in the [genuine] language, (TA,) plural طُمُونٌ. (K.) Hence one says, هُوَ مُطْمَيءِنٌّ إِلَى كَذَا (tropical:) He is trusting to such a thing, or relying upon it, so as to be at rest or ease, or quiet, in mind. (S, K, * TA.) And [it is said that] النَّفْسُ المُطْمَيءِنَّةُ means (assumed tropical:) The soul that has become at rest or ease, quiet, or calm, by belief; and lowly, humble, or submissive, to its Lord. (TA. [See the Qur'an, 89:27.])
3.
Also Taking for oneself a place in the earth, or in a country, as a home, or settled place of abode. (TA.)
