Is repentance accepted after sinning and then returning to it while feeling guilty? What are the characteristics of a righteous woman? And how can the heart remain steadfast on the right path and maintain prayer?

Allah accepts the repentance of His servants, no matter how great the sin or how often it is repeated, if the repentance is sincere and fulfills its conditions of remorse, determination not to return to the sin, and immediate cessation. One who repents from a sin is like one who has no sin. Steadfastness of the heart on the right path and adherence to obligations are achieved by seeking help from Allah the Almighty and supplicating to Him, accompanying the righteous, constantly contemplating the Hereafter, and continuously reflecting on Allah's names and attributes while being mindful of His constant observation of His servant.
