حرس1 حَرَسَهُ, (S, A, Mgh, Msb, K,) aor. ـُ (S, Msb, TA) and حَرِسَ (TA,) inf. n. حِرَاسَةٌ (S, Mgh, K) and حَرْسٌ, (K,) or ↓ the former is a simple subst., (Msb,) and the latter is an inf. n. only on the authority of analogy, though often used by [the Hanafee Imám] Mohammad, (Mgh,) He guarded, kept, preserved, or took care of, him or it: (S, Mgh, Msb:) [and so ↓ حارسهُ; or he guarded him, being guarded by him: see 3 in art. ربأ.] You say, حَرَسَهُ اللّٰهُ مِنَ البَلَآءِ [May God guard him from trial, or affliction]: and أَدَامَ حِرَاسَتَهُ [May He continue the guarding of him]. (A.) b2:  حَرَسَ, aor. ـِ (Msb, K,) inf. n. حَرْسٌ, (Msb,) (tropical:)  He stole; (Msb, K;) [ironically used in this sense; see حَارِسٌ;] as also ↓ احترس: (K:) or the latter, he stole a sheep or goat by night: (S:) or both, he stole camels and sheep or goats by night, and ate them: (TA:) or the latter, he stole [a sheep or the like] from the mountain: (El-Fárábee, Msb:) or he took, (Sh, TA,) or stole, (TA,) a thing from the place of pasturage. (Sh, TA.) Yousay also, حَرَسَنِى شَاةً, (A, Mgh,) and ↓ أَحْرَسَنِى, (A, TA,) [but the latter is perhaps a mistranscription for ↓ اِحْتَرَسَنِى,] (tropical:)  He stole from me a sheep or goat. (Mgh.) 3 حَاْرَسَ see above.4 أَحْرَسَ see 1, last signification.5 تحرّس مِنْهُ, and منه ↓ احترس, He guarded, i. e., guarded himself, against him; syn. تحفّظ منه (S, Msb, K.) 3 حَاْرَسَ see 5: A2:  and see حَرَسَ, in two places.حَرَسٌ: see حَارِسٌ: for the former, in two places.حَرَسِىٌّ: see حَارِسٌ: for the former, in two places.حِرَاسَةٌ: see 1.A2:  فُلَانٌ يَأْكُلُ الحِرَاسَاتِ Such a one eats stolen things: (A:) or steals the sheep or goats of people, one after another, and eats of them. (TA.) حَرِيسَةٌ What is guarded, kept, preserved, or taken care of. (Msb.) b2:  (tropical:)  A thing stolen: (K:) or a sheep, or goat, that is stolen by night: (S:) of the measure فَعِيلَةٌ in the sense of the measure مَفْعُولَةٌ: (TA:) hence, حَرِيسَةُ الجَبَلِ (S) a sheep, or goat, that is overtaken by the night before its return to its nightly resting-place, and is stolen from the mountain: (Msb:) or a sheep, or goat, that is stolen, of those that are guarded, or kept, in the mountain: or, as some say, from حَارِسٌ applied ironically to a thief: (Mgh:) pl. حَرَائِسُ (S, K.) Hence the saying, (TA,) لَا قَطْعَ فِى حَرِيسَةِ الجَبَلِ (tropical:)  [There shall be no amputation of the hand for the sheep, or goat, that is stolen by night from the mountain]. (A, TA.) IF says that there are two explanations of the expression حريسة الجبل: some make it to signify theft, or the thing stolen, (السَّرِقَةُ,) itself: others make the meaning to be, that there shall be no amputation for [stealing] what is guarded, or kept, in the mountain, because it is not a place well protected: ISk says that الحَرِيسَةُ signifies السَّرِقَةُ. (Msb.) b3:  A wall of stones, made for sheep, or goats, (K,) to guard them. (TA.) حَارِسٌ Guarding, keeping, or preserving; a guardian, or keeper: (S, Mgh, Msb:) pl. ↓ حَرَسٌ (Mgh, Msb, K) [or this is rather a quasi-pl. n.] and حُرَّاسٌ (Msb, K) and [pl. of pauc.] أَحْرَاسٌ. (K.) ↓ حَرَسٌ also signifies The guards of a Sultán; (S, * Msb, K TA;) and so حُرَّاسٌ: (S, K:) the former is thus used as a gen. n.: (S, Msb:) and the n. un. is ↓ حَرَسِىٌّ: (S, Msb, K:) you do not say حَارِسٌ unless you mean to denote thereby the signification of guarding, or keeping, without the quality of a gen. n. (S, Msb.) b2: Also (tropical:)  A thief; used in this sense ironically; (A, Mgh, TA;) because they found guardians to be thieves; (A, TA;) and so ↓ مُحْتَرِسٌ: (TA:) pl. of the former, حُرَّاسٌ. (A.) مُحْتَرَسٌ [pass. part. n. of 8]. You say, مُحْتَرَسٌ مِنْ مِثْلِهِ وَهْوَ حَارِسٌ [From such as he does one guard himself, whereas he is a guardian]: a prov.: (S, K:) alluding to him who finds fault with a bad man when he is himself worse than he: (K:) or to him who is intrusted with the guarding of a thing when one is not secure from his being unfaithful with respect to it. (TA.) [See also Freytag's Arab. Prov., ii. 706.]مُحْتَرِسٌ: see حَارِسٌ, last signification.
