وجب

وَاجِبٌ ذ Slain: (S:) dying; or dead. (TA.) So in the following verse of Keys Ibn-ElKhateem: أَطَاعَتْ بَنُو عَوْفٍ أَمِيرًا نَهَاهُمُ عَنِ السِّلْمِ حَتَّى كَانَ أَوَّلَ وَاجِبِ [ The sons of 'Owf obeyed a commander who forbade them to make peace until he was the first who was slain, or who died ]. (S, TA.) -A2- وَاجِبٌ [act. part. n. of وَجَبَ; Necessary; requisite; unavoidable: binding, incumbent, or obligatory. In the science of the fundamentals of religion, Necessarily being or existing; of which the nonexistence cannot be mentally conceived: as the essence of God. (IbrD.)] ― -b2- Accord. to [the Imám] Aboo-Haneefeh, وَاجِبٌ [in matters of religion] is not so strong a term as فَرْضٌ: [and so may be rendered incumbent, or obligatory; or that which is a necessary, or indispensable, duty; yet not so decisively or manifestly shown to be such as that which is termed فرض:] or, accord. to Esh-Sháfi'ee, these two terms are syn., signifying [ binding, incumbent, or obligatory, by God's express appointment, as ] a thing for neglecting which one will be punished: and واجب signifies that which should be preferred and approved; thus explained by ElKhattábee as occurring in the following trad.: غُسْلُ الجُمْعَةِ وَاجِبٌ عَلَى كُلِّ مُحْتَلِمٍ The ablution prescribed to be performed on Friday is an act which every one who has experienced a nocturnal pollution should prefer and approve. (TA.) -A3- فِعْلٌ وَاجِبٌ [ A verb expressing an event as a positive fact ] is such, for instance, as in the phrase بَيْنَمَا أَنَا كَذَا اـِذْ جَاآءَ زَيْدٌ [while I was thus, or in [this state, lo, or behold, Zeyd came]. (S, L, art. اذ.)
