What is the advice and guidance for getting rid of my sins of masturbation and looking at scantily clad women, with the repeated failed attempts and frequent repentance, and how can one reconcile between calling to Allah and this state of sins?

Praise be to Allah for guidance, and we ask Allah to bestow upon you sincere repentance from forbidden looking and masturbation. Strive against yourself and rely on Allah, and take the means to abstain from sin before death, with the importance of supplicating to Allah and imploring Him. Fast voluntary fasts to break desire, and avoid places of immodestly dressed women. Be keen on righteous companionship, and persevere in calling to Allah, for falling into sin does not justify abandoning the call to Allah.
