رحب1 رَحُبَ, (Msb, K,) said of a place, (Msb,) or of a thing, (TA,) and رَحُبَتْ, said of a land, (أَرْض, S,) or of a country, (بِلَاد, A, TA,) aor. ـُ inf. n. رُحْبٌ (S, A, * Msb, K) and رَحَابَةٌ; (S, K;) and رَحِبَ, (Msb, K,) and رَحِبَتْ, (TA,) aor. ـَ (Msb, K,) inf. n. رَحَبٌ; (Msb, TA;) and ↓ ارحب, (Msb, K,) and ارحبت; (TA;) It was, or became, ample, spacious, wide, or roomy. (S, K, TA.) رَحُبَتِ الدَّارُ and ↓ أَرْحَبَت both signify the same, i.e. The house, or abode, was ample, &c.; or may the house, or abode, be ample, &c. (S, TA.) and they said, عَلَيْكَ وَطُلَّتْ ↓ أَرْحَبَتْ, meaning May it (the country, البِلَادُ,) be spacious to thee, and be moistened by gentle rain, or by dew: so accord. to Aboo-Is-hák. (TA.) ضَاقَتْ عَلَيْهِمُ الأَرْضُ بِمَا رَحُبَتْ, in the Kur ix. 119, means The earth became strait to them with [i. e. notwithstanding] its spaciousness. (Bd, Jel.) b2:  رَحُبَ, accord. to the original usage, is trans. by means of a particle; so that one says, رَحُبَ بِكَ المَكَانُ [The place was, or may the place be, spacious with thee]: afterwards, by reason of frequency of usage, it became trans. by itself; and thus one said, رَحُبَتْكَ الدَّارُ [The house, or abode, was, or may the house, or abode, be, spacious with thee, or to thee]. (Msb.) b3:  [Hence the saying,] أَرَحُبَكُمُ الدُّخُولُ فِى طَاعَتِهِ (assumed tropical:)  Was it proper, or allowable, for you [to enter among his obeyers? i. e., to become obedient to him?]: (S, K * TA:) referring to El-Kirmánee, (so in the S,) or Ibn-El-Kirmánee: (so in the TA:) mentioned by Kh, on the authority of Nasr Ibn-Seiyár; but he says, (S,) the verb thus used is anomalous; (S, K;) for a verb of the measure فَعُلَ is not trans., (K, TA,) accord. to the grammarians, (TA,) except  with the tribe of Hudheyl, who, accord. to AAF, make it trans. (K, TA) when its meaning admits of its being so: (TA:) Kh mentions the phrase رَحُبَتْكُمُ الدَّارُ [meaning The house, or abode, was, or may the house, or abode, be, spacious with, or to, you]; but it is thought that there is an ellipsis here, and that it is for رَحُبَتْ بِكُمُ الدَّارُ: and ElJelál Es-Suyootee mentions, on the authority of AAF, the saying رَحُبَ اللّٰهُ جَوْفَهُ, as meaning وَسَّعَهُ [i. e. May God make wide his belly]: (TA:) [J says, app. quoting Kh,] there is no sound verb of the measure فَعُلَ that is trans. except this; but as to the unsound, there is a difference of opinion: accord. to Ks, قُلْتُهُ is originally قَوُلْتُهُ; but Sb says that this is not allowable, because it is trans.: (S:) Az says that رَحُبَتْكُمْ is not held to be allowable by the grammarians; and that Nasr is not an [approved] evidence. (TA.) 2 رَحَّبَ see 4. b2:  رحّب بِهِ (S, A, Msb, K,) inf. n. تَرْحِيبٌ (S, A, K) and تَرْحَابٌ (Har p. 579,) He said to him مَرْحَبًا; (S, Msb;) [he welcomed him with the greeting of مَرْحَبًا; or simply he welcomed him;] he invited him to ampleness, spaciousness, or roominess: (A, K:) and ↓ مَرْحَبَ, also, signifies he said مَرْحَبًا; but the expression commonly known is رَحَّبَ بِهِ. (Har pp. 422-3.) You say, لَقيتُهُ بِالتَّرْحِيبِ [I met him with the greeting of مَرْحَبًا; or with welcoming]. (A.) See also مَرْحَبٌ4 أَرْحَبَ see 1, in three places.A2:  ارحبهُ He made it (a thing, S) ample, spacious, wide, or roomy; (S, K;) as also ↓ رحّبهُ. (CK. [The latter is not in the TA, nor in my MS. copy of the K.]) El-Hajjáj said, when he slew Ibn-El-Kirreeyeh, أَرْحِبْ يَا غُلَامُ جُرْحَهُ [Make wide, O young man, his wound]. (S.) And one says, in chiding a horse or mare, أَرْحِبْ (S, K) and أَرْحِبِى (S, A, K,) meaning Make room, and withdraw. (S, A, K.) 6 تَرَاْحَبَ An instance of this verb occurs in the saying, هٰذَا الأَمْرُ إِنْ تَرَاحَبَتْ مَوَارِدُهُ فَقَدْ تَضَايَقَتْ مَصَادِرُهُ (tropical:)  [This affair, or case, if the ways leading to it, or the ways of commencing it, be easy, the ways of return from it, or the ways of completing it, are difficult].

(Ham p. 721.) and ↓ اِمْرَأَةٌ رُحَابٌ A wide woman; (K;) meaning wide in respect of the فَرْج. (TK.) And رَجُلٌ الجَوْفِ ↓ رَحِيبُ A man ample, or wide, in the belly: and, as mentioned by Es-Suyootee, (assumed tropical:)  a great eater; voracious; (TA;) and so رَحِيبٌ alone. (S, K, TA.)

And hence the saying of Zeyd Ibn-Thábit to 'Omar, هٰهُنَا بِالرُّحْبِ, meaning Advance to ampleness, &c. (Mgh.) See also مَرْحَبٌ, in two places. b2:  [It is also used as an epithet:] see the next preceding paragraph.رَحَبٌ: see the next following paragraph.رَحَبَةٌ, (S, A, Mgh, Msb, K) and رَحْبَةٌ, (A, Mgh, Msb,) K,) the former of which is the more chaste, (A,) or the better, (Mgh,) or the more common, (Msb,) The court, open area, or spacious vacant part or portion, (S, A, Mgh, Msb, K,) of a mosque, (S, A, Mgh, Msb,) and of a house, (A, TA,) or of a place; (K;) so called because of its ampleness: (TA:) and in like manner, between, or among, houses: (A:) a desert tract, (Fr, Mgh, TA,) or a spacious vacant tract, (A,) or a spacious piece of ground, (Msb,) between, or among, the yards of the houses of a people: (Fr, Mgh, Msb, TA:) and sometimes thus is termed an enclosure, or a [kind of wide bench of stone or brick such as is called] دُكَّان, that is made at the doors of some of the mosques in the towns and the rural districts, for prayer: hence the saying of Aboo-'Alee Ed-Dakkák, [in which it means an enclosure outside the door of a mosque,] “ It is not fit that the حَائِض should enter the رحبْة of the mosque of a people, whether the رحبة be contiguous or separate: ” and hence, also, in a trad. of 'Alee, by the رحبة of El-Koofeh is meant a دُكَّان in the midst of the mosque of El-Koofeh, upon which he used to sit and to preach, and upon which he is related to have cast the spoils that he obtained from the people of En-Nahrawán: (Mgh:) pl. ↓ رَحَبٌ (S, Msb, K) and ↓ رَحْبٌ (K) [or rather these are coll. gen. ns. of which رَحَبَةٌ and رَحْبَةٌ are the ns. un.] and [the pl. is] رِحَابٌ and رَحَبَاتٌ (S, Msb, K) and رَحْبَاتٌ. (K.) b2: Also, both words, An ample tract of land, that produces much herbage, and in which people alight, or abide, much, or often: (AHn, K:) pl. as above, accord. to the K; but accord. to IAar, رَحْبَةٌ signifies an ample tract of land; (TA;) and he says that its pl. is رُحَبٌ, like as قُرًى is pl. of قَرْيَةٌ: Az says that this occurs as an anomalous pl. of words of the defective class, and that he had not heard a word of the perfect class of the measure فَعْلَةٌ having a pl. of the measure فُعَلٌ; but that IAar is an authority worthy of reliance.
