رَجَبٌ

One of the [Arabian] months; (Msb;) [namely, the seventh thereof;] so called because of the honour in which it was held in the Time of Ignorance, (S, A, * K, *) inasmuch as war, or fighting, during it was held unlawful: (S:) in a tradition, (TA,) it is called رَجَبُ مُضَرَ [Rejeb of Mudar], because Mudar most honoured it: (S, TA:) and it is further distinguished as being between جَمَادَى and شَعْبَان, to show that what is meant by it is not what the [pagan] Arabs called رجب according to the computation founded upon postponement; for they used to postpone it from month to month: (TA:) [it is also called رَجَبٌ الفَرْدُ Rejeb the separate; because it is the only sacred month that is not preceded nor followed by another sacred month; the other sacred months being المُحَرَّمُ and ذُو القَعْدَةِ and ذُو الحَجَّةِ:] the plural is أِرْجَابٌ (S, Msb, K) and أَرْجِبَةٌ and أَرْجُبٌ [all pls. of pauc.] (Msb) and رُجُوبٌ and رِجَابٌ and رَجَبَاتٌ (Msb, K) and رَجُوبٌ [or rather this last is a quasi-plural n.] (TA) and [plural plural] أَرَاجِبُ [plural of أَرْجُبٌ] and أَرَاجِيبُ [plural of أَرْجَابٌ]. (Msb.) The dual, رَجَبَانِ, (S, Msb,) or الرَّجَبَانِ, (A,) [The two Rejebs] is applied to [the two months] رَجَبٌ and شَعْبَانُ, (S, A, Msb,) by the attribution of predominance to the former. (Msb.)
