What is the ruling on kissing a friend on the mouth? Is it permissible to break the fast in Ramadan due to strenuous work? What is the expiation for intentionally breaking the fast during Ramadan? Is there a way to repent from sodomy? And is the repentance of one who swears and promises not to return to sin, then returns to it, accepted?

A man kissing another man on the mouth is impermissible, and sodomy is a major sin. Repentance is achieved through intense remorse and a firm resolve not to return to the sin. Intentionally breaking the fast in Ramadan (definition) after puberty is among the major sins. The door of repentance is open, so you must repent to Allah and make up the days of Ramadan you missed. Compensation by feeding the poor instead of making up the fast is only permissible for those who are permanently unable to fast. Your return to sin after repentance should not prevent you from repenting again. Among the means to achieve steadfastness are: observing acts of obedience, attending scholarly gatherings, frequently engaging in remembrance of Allah, befriending righteous people, and abandoning bad company.
