Repentance And Forgiveness
It’s never too late. We should repent to God with complete sincerity of heart and ask for forgiveness and mercy. True repentance is one which transforms our actions. We should try our best to not be negligent in our prayers and offer all our obligations to God in the most fitting manner. For the missed salah, Ahsan sahab has shared the thread. For the missed fasts, one can do niyyat to offer them and keep fasts occasionally in order to complete them over the course of time. In addition, it’s important to keep strengthening our Iman to avoid falling back into the previous state. The following video might be helpful in this regard: https://youtu.be/TudZTl35No0
