(TA.) b2: Also She attained the age of menstruation. (TA.) [See حَائِضٌ.] b3:  حَاضَتِ السَّمُرَةُ, (S, A, Msb,) aor. as above, (Msb,) inf. n. حَيْضٌ, (S, Msb,) (tropical:)  The سمرة [or gum-acacia-tree] flowed with, (S,) or emitted, (A,) a matter resembling blood; (S, A;) flowed with its gum: (Msb:) the matter which it emits is called دُوَدِم; and is applied to the head of a new-born infant to scare away the jánn, or genii. (A, TA: [but in a copy of the A, and in one instance in the TA, الشَّجَرَةُ is put in the place of السَّمُرَةُ, app. by mistake.]) [I have marked this signification as tropical on the authority of the A and TA; but the author of the Msb has commenced the art. with it; and shows that he held the opinion, which some others have shared with him, that it is the primary signification.] b4: حَاضَ السَّيْلُ (assumed tropical:)  The torrent overflowed; or poured out, or forth, from fulness; or ran; syn. فَاضَ. (TA.) 2 حيّض المَرْأَةَ He attributed حَيْض [or menstruation] to the woman. (Msb.) b2:  حيّض جَارِيَتَهُ, (TK,) inf. n. تَحْيِيضٌ, (Sgh, K,) Tempore men-struorum inivit ancillam suam.

(TA.) 10 اُسْتُحِيضَتْ, (S, Mgh, Msb,) in the pass. form, (Msb,) with damm to the ت, (Mgh,) [as though originally signifying She was reckoned to be menstruating,] found in the handwriting of Aboo-Zekereeyà اِسْتَحْيَضَتْ, (TA,) [which I hold to be a mistake, as being at variance with general usage,] She continued to have a flow of blood (S, Mgh) after her days [of menstruation]: (S:) or she had an exuberance of blood [flowing from the vagina]; not what is termed الحَيْض: (Msb:) or her blood flowed without stopping, not on certain days, nor from the vein [or veins] of menstruation, but from a vein called العَاذِلُ. (TA.) حَيْضٌ [an inf. n. of 1: explained in the KT as applied to The menstrual blood itself; which seems to have been more properly called حِيضَةٌ and مَحِيضٌ and حِيَاضٌ: though what here follows may be considered as rendering it probable that حَيْضٌ was also used in this sense in the classical times, for دَمُ حَيْضٍ]. b2:  حَيْضُ السَّمُرِ (assumed tropical:)  A thing which flows from the سَمُر [or gum-acacia-trees], resembling [what is called] دَمُ الغَزَالِ. (Mgh.) [See also 1.]حَيْضَةٌ A single time, or turn, of menstruation, or of the flow of the menstrual blood: (S, * A, * Mgh, Msb: *) pl. حِيَضٌ; (A, Msb;) like as بِدَرٌ is pl. of بَدْرَةٌ, and ضِيَعٌ of ضَيْعَةٌ, and حِيَدٌ of حَيْدَةٌ, and خِيَمٌ of خَيْمَةٌ; though by rule it should be حَيْضَاتٌ. (Msb.) You say, حَاضَتْ حَيْضَةً وَاحِدَةً[She menstruated one single time of menstruation]: and حَيْضَةً طَوِيلَةً [a long single time thereof]: and ثَلَاثَ حِيَضٍ [three single times thereof]. (A.) b2: As used by the professors of practical law, The accustomed days thereof. (Mgh.) b3: Also (assumed tropical:)  A single flow [of water &c.]: pl. حَيْضَاتٌ. (TA.) حِيضَةٌ [Menstruation;] the subst. from حَاضَتِ المَرْأَةُ: (S, K, TA:) or a mode, or manner, or state, of حَيْض [or menstruating]: (Msb:) or the state (Mgh, TA) of the حَائِض, (TA,) which is one of avoidance (Mgh, TA) of prayer and fasting and the like: (Mgh:) pl. حِيَضٌ. (S, Msb.) b2:  Also The menstrual blood; the blood of menstruation; and so ↓ مَحِيضٌ and ↓ حِيَاضٌ. (TA.) [See also حَيْضٌ.] b3:  Also The piece of rag which the حَائِض binds over her vulva; (S, Mgh, * Msb, * K;) and so ↓ مَحِيضةٌ: (S:) which  latter also signifies (assumed tropical:)  a piece of rag thrown away: (TA:) pl. of the latter, مَحَايِضُ. (S, TA.) حَيْضِىٌّ Menstrual; of, or relating to, menstruation.]حِيَاضٌ: see حِيضَةٌ.حَائِضٌ, applied to a woman, [Menstruating;] act. part. n. from حَاضَتْ; (S, Mgh, Msb, K;) thus, [without ة,] because it is an epithet of particular application [to a female]; (Msb;) and with ء, being like قَائِمٌ and صَائِمٌ &c.; (TA;) [because the ى in its verb suffers alteration;] and in like manner حَائِضَةٌ also, (S, Mgh, Msb, K,) on the authority of Fr: (S:) pl. (of the former, Msb) حُيَّضٌ, (S, Mgh, Msb, K,) like as رُكَّعٌ is pl. of رَاكِعٌ, (Msb,) and حَاضَةٌ, like as حَاكَةٌ is pl. of حَائِكٌ, (TA,) and of the latter, حَائِضَاتٌ, (Msb,) or حَوَائِضُ. (S, Mgh, K.) b2: In a certain trad., in which it is said that God will not accept the prayer of a حَائِض unless she be [attired] with a خِمَار [or head-covering], this does not mean one who is menstruating while actually occupied by prayer, (Msb, TA, *) but (assumed tropical:)  One who has attained to the age of menstruation; (TA;) or one who has attained to womanhood: (Mgh:) or it has not this meaning; for if it had, one would understand that a girl not arrived at puberty might pray with her head uncovered, which is not the case; but it means (tropical:)  [one of] the menstruating kind, whether she have attained to puberty or not; as though the term female had been used in its place. (Msb.) مَحِيضٌ is a simple subst. as well as an inf. n.: (Zj, K:) as the former, it is a n. of place; and as such it is [said to be] used in the Kur ii. 222; meaning A woman's مَأْتًى; (Zj;) her فَرْج; (Mgh;) because it is the place of الحَيْض. (Zj, Mgh.) Some  say that حَوْضٌ is hence derived; because the water flows to the حوض: (Az, K:) for the Arabs put و in the place of ى, and ى in that of و. (Az, TA.) b2:  It is also a n. of time [signifying The time of menstruating]. (TA.) b3:  See also حِيضَةٌ. b4:  When it is a simple subst., it has a pl., namely مَحَايِضُ. (TA.) مَحِيضَةٌ: see حِيضَةٌ.مُسْتَحَاضَةٌ A woman continuing to have a flow of blood after her days [of menstruation]: (S:) or having an exuberance of blood [flowing from her vagina]; not what is termed الحَيْض: (Msb:) or having her blood flowing without stopping, not on certain days, nor from the vein [or veins] of menstruation, but from a vein called العَاذِلُ.
