Ji haan, Shab E Qadr ki raat ko ibadat karne se gunahon ki maafi mil jati hai, agar dil se tauba aur astaghfar ke saath ibadat ki jaye. Allah Ta'ala apne bandon ki gunahon ko maaf farma dete hain.Baaz log is raat me raat ke aakhir hisse Tak jagte hain, fir so jate hain. Is tarah unki fazr ki namaz qaza ho jati hai, jo sahi nahi hai. *Hadees Shareef
