Rajab (ِArabic: رجب) is the seventh month of the Islamic calendar. The lexical definition of the classical Arabic verb rajaba is "to respect" which could also mean "be awe or be in fear", of which Rajab is a derivative.
This month is regarded as one of the four sacred months in Islam in which battles are prohibited. The pre-Islamic Arabs also considered warfare blasphemous during the four months.
Muslims believe Rajab is the month in which ‘Alī ibn Abī Tālib, the first Imam of [and Fourth Caliph of , was born. Rajab is also the month during which Isra' Mi'raj (journey from Mecca to Jerusalem and then to heaven) of the Islamic prophet, Muhammad, took place.
There will be an Ayah (sign) in (the month of) Ramadan. Then, there will 'isabah (splitting into groups) in Shawwal. Then, there will be fighting in (the month of) Dhu al-Qi'dah. Then, the pilgrim will be robbed in (the month of) Dhu al-Hijjah. Then, the prohibitions will be violated in (the month of) al-Muharram. Then, there will be sound in (the month of) Safar, then the tribes will conflict with each other in the two months of Rabi' al-awwal & Rabi' al-thani. Then, the most amazing thing will happen between (the months of) Jumada and Rajab. Then, a well-fed she-camel will be better than a fortress (castle) sheltering a thousand (people).[not specific enough to verify]
The Islamic calendar is a lunar calendar, and months begin when the first crescent of a new moon is sighted. Since the lunar year is 11 to 12 days shorter than the solar year, Rajab migrates throughout the seasons.
