Sincerity when making Tawbah

Q 3: What is the ruling on someone who repents then returns to the same sin again later on?

A: If someone repents sincerely of the sin, gives it up and regrets it, but Satan and his own evil instincts overpower him into sinning again, this will not undo his repentance. He should repent of (Part No. 24; Page No. 319) sinning again as well as avoid the means leading to sins.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
