Read this Dua daily in the morning and at night before sleeping.
Prophet Muhammad (Sal Allahu Alayhi Wa Sallam) said, "Whoever makes this dua during the day with firm belief in it and dies on the same day (before the evening) he will be one of the dwellers of Jannah (Paradise); and whoever makes this dua during the night with firm belief in it and dies before the morning, he will be one of the dwellers of Jannah (Paradise).”

Al-Bukhari

Astaghfar ka wazifa:

Astaghfar ki fazilat se hum sab waqif hain, Allah bohat ghafoor o raheem hain. Jo shakhs Allah se schay dil se maafi mangta ha Allah us ko zaroor maaf farma detay hain.
Jo Shakhs ye astaghfar ki dua parhay ga us ke liay bohat bara inaam hai,
Jo shakhs astaghfar ki dua subha uthtay sath he parhay aur usi din foat ho jaye tou wo jannat mai jaye ga.
Esi tarah jo shakhs raat ko sonay se pahlay astaghfar ki dua parhay aur foat ho jaye tou wo jannat mai jaye ga,

Allah hum sab ko amal arne ki toufeeq ata farmaye.. ameen,
