Allah has told us that He will forgive all sins for the one who repents to Him, even Shirk. Whoever repents, Allah will accept his repentance. To repent from Shirk, all you have to do is to turn to Allah, regret what you did and resolve not to do it again. In general, faith is increased by doing acts of worship and keeping away from prohibited things.

Kissing one’s wife in front of people is not permissible. Kissing one’s wife in public does not constitute Zina because there is no Zina with one’s wife. There is no expiation for this kissing the wife in public except sincere repentance and firm resolve not to do it again, and true regret for having committed this sin.

With regard to masturbation, the basic ruling is that it is prohibited according to the majority of scholars, and the one who does it should be given a Ta`zir punishment, but it is not like Zina.

Allah has not commanded the person who repents to do Wudu or Ghusl, whether his impurity is minor or major, either before or after repenting, unless he is repenting from disbelief or apostasy.

A false oath may be expiated by sincere repentance. There is no sin for which repentance cannot be accepted, for Allah has opened the door of repentance to every sinner.

1. Faith increases by doing acts of worship and righteous deeds, and it decreases by committing sins. So whoever wants to increase his faith, let him focus on obeying Allah and let him avoid disobeying Him. What will help him to do that is spending time with righteous people and keeping away from innovators and sinners. 2. The remedy for intrusive thoughts (Waswas) is to ignore them and turn away from them; to recite a great deal of Quran; to do great deal of righteous deeds; and to call upon Allah, may He be Glorified, and beseech Him to ward off the schemes of the Shaytan from you and to make you steadfast in adhering to the truth.

All this person who mistreated his parents has to do now is hasten to repent for Allah has promised to accept the repentance of the one who repents. Regretting mistreating his parents is repentance in itself. After a parent’s death, one can honour them by making a lot of du`a from them, doing righteous deeds on their behalf, and honouring their friends and loved ones.
