Ibn Rajab al-Hanbali mentions in Lata’if al-Ma’arif:
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.” It has similarly been related from him: “Rajab is like the wind; Sha’ban is like the water-laden clouds; and Ramadan is like the rain.” Someone else mentioned: “The year in its entirety is like a tree: during Rajab its buds sprout; during Sha’ban it sends forth its branches; during Ramadan its fruit ripens; and the believers are the farmhands who harvest that fruit.”
