Fasting is intended to teach Muslims about patience, humility, and spirituality. It is a time for Muslims to fast for the sake of God and to offer more prayer than usual. During Ramadan, Muslims ask forgiveness for past sins, pray for guidance and help in refraining from everyday evils, and try to purify themselves through self-restraint and good deeds. As compared to the solar calendar, the dates of Ramadan vary, moving backwards about eleven days each year depending on the moon. Muslims believe Ramadan to be an auspicious month for the revelations of God to humankind, being the month in which the first verses of the Qur'an were revealed to the Islamic prophet, Muhammad.
The name "Ramadan" had been the name of the ninth month in Arabian culture long before the arrival of Islam; the word itself derived from an Arabic root rm, as in words like denoting intense heat, scorched ground and shortness of rations. In the Qur'an, God proclaims that "fasting has been written down (as obligatory) upon you, as it was upon those before you". According to the earliest hadith, this refers to the Jewish practice of fasting on Yom Kippur.
