Is Tawfiqullah (God's granting of success) forbidden from diligent study due to listening to songs and watching clips of kisses and embraces?

If the singing listened to is forbidden, and watching clips containing kisses and embraces is a reprehensible act, then one must repent from all of that, because sins have serious consequences for the one who commits them in this world and the Hereafter. They may also deprive one of success in studies. Therefore, sincere repentance and taking the path of righteousness are advised.
