All the deeds of the adam will be multiplied (in return), one good will be rewarded with 10 to 700 fold. "Allah Swt. says: "Unless fasting, it is for Me, and I repay it immediately. My servant has abandoned lust and food for me. "(Muslim)
During the month of Ramadan we are commanded to uphold the obedience to Allah SWT, in addition to performing the obligations of fasting. Many of the deeds of worship that we do as a form of establishing the month of Ramadan, among which is praying qiyamul lail and reading the Qur'an. As Imam Al-Shan'any wrote in his book Subulus Salam:
"Upholding the month of Ramadan, which is to establish the night of Ramadan with prayer or reciting the Qur'an." (Juz II, p. 173)
