Rajab

The seventh month of the Islamic calendar marks the beginning of the spiritual season with its climax being the month of Ramadhan.
On sighting the new moon of Rajab, The Prophet (pbuh) used to pray saying: "O Allah, make the months of Rajab and Sha'ban blessed for us, and let us reach the month of Ramadhan (i.e. prolong our life up to the month of Ramadhan, so that we may benefit from its merits and blessings)."
The Prophet (pbuh) also said: "Indeed Rajab is a month unmatched by any other month in the respect and significance (accorded to it)... Rajab is Allah's month, Sha'ban my month and Ramadhan the month of my followers."

Imam Ali (pbuh) used to fast for the entire month of Rajab.

Rajab is also one of the sacred months mentioned in the Qur'an:
"Surely the number of months with Allah is twelve months in Allah's ordinance since the day when He created the heavens and the earth, of these four being sacred..." 9:36
These being Dhulqa'da, Dhulhijja, Muharram and Rajab.
