The Holy month of Rajab ( 重要的伊斯蘭曆 7 月)

Rajab is the seventh month of the Islamic calendar. 

This month is regarded as one of the four sacred months in Islam in which battles are prohibited. 

The month is also a prelude to the month of Ramadan, which follows after the intervening month of Sha'ban.

Therefore, when Prophet Muhammad sighted the moon of Rajab, he used to pray to Allah 
in the following words:

Allahumma baa-rik-lanaa fee-rajaba wa sha'bana wa bal-lig-naa  ramadana

"O Allah, make the months of Rajab and Sha'ban blessed for us, and let us reach 
the month of Ramadan

(May  ALLAH prolong our life up to Ramadan, so that we may benefit from its merits and blessings)

shiekh Hamzah yusuf said :

The month of Rajab is the key to the months of goodness and blessings that follow it. 

Abu Bakr b. al-Warraq al-Balkhi said:

 “Rajab is the month to sow the seeds; Sha’ban is the month to irrigate the crop; 
and Ramadan is the month to reap the harvest.”

A poet said:

So cleanse your darkened hearts within Rajab;
with deeds that spare the soul Hellfire’s wrath.

One of the sacred months has come along;
no one who calls on God will be forlorn.

Heaven is for the one’s who cleanse their hearts
with lewd indecent deeds they’ll have no part.

Taking advantage of the opportunity to do righteous deeds during this month is a source
 of great gain. While filling each moment of the month worshiping God is a bounteous virtue.
