Hojat-ol-Islam Tahmasb Hatami said everyone should make the most of this month and there are Duas (supplications) in this regard that should be recited several times every day, including Astaghfirulaha wa as’aluhut Tawba (I ask Allah for forgiveness and I pray to Him to accept my repentance), and La Ilaha Illa Allah (There is no God but Allah).
