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.
The month is also a prelude to the month of Ramadan, which follows after the intervening month of Sha'ban. When Muhammad sighted the moon of Rajab, he used to pray to Allah in the following words:
اللّهمّ بارك لنا في رجب و شعبان وبلّغنا رمضان
Allāhumma bārik lanā fī rajaba wa shaʻbāna wa balligh-nā ramaḍāna
"O Allah, make the months of Rajab and Sha'ban blessed for us, and let us reach the month of Ramadan (i.e. prolong our life up to Ramadan, so that we may benefit from its merits and blessings)."
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. The estimated start and end dates for Rajab, based on the Umm al-Qura calendar of Saudi Arabia, are:
|AH||First day (CE / AD)||Last day (CE / AD)|
|1431||13 June 2010||12 July 2010|
