And while performing the ghusl for janabah, you should say: "O Allah سبحانه وتعالى, purify my heart, purify my deeds, accept my efforts, and make what is with You better for me." In another narration, it is mentioned: Imam عليه السلام said: "O Allah سبحانه وتعالى, make me among those who repent often, and make me among those who purify themselves."
