What is the expiation for a kiss, and do the day's deeds, such as prayers and acts of obedience, atone for it for a married person?

A kiss that is impermissible due to being from the prohibited "lamam" (minor sins) is expiated by avoiding major sins, performing the obligatory prayers, and engaging in various acts of devotion. There is a difference of opinion regarding the meaning of "lamam"; some say it encompasses everything short of zina (fornication), while others say it refers to everything short of sexual intercourse, such as a kiss, a wink, a glance, or intimate lying together. The five daily prayers, the Friday prayer until the next Friday prayer, and Ramadan until the next Ramadan are expiations for what occurs between them, provided major sins are avoided. The commission of a sin by a chaste person is more reprehensible, and persistence in minor sins can transform them into major ones.
