Ramadan is the only month mentioned by name in the Qur’an. Muslims fast the ninth month of Ramadan in the Hijri calendar.
The root “r m d’ indicates the meaning of sharpness in something like hot and other things. The ancients used this intense heat to hunt antelope. As for wintering sheep, it means grazing in extreme heat. It happened in Ramadan when the sun of Islam shone on the Babylonian fortress in Egypt. It is a season of forgiveness, a station for righteousness and benevolence.
