I'tikaf in Ramadan
Malik :: Book 19 : Hadith 19.5.9
Malik said, "There is no harm in someone who is in itikaf entering into a marriage contract as long as there is no physical relationship. A woman in itikaf may also be betrothed as long as there is no physical relationship. What is haram for someone in itikaf in relation to his womenfolk during the day is haram for him during the night."
Yahya said that Ziyad said that Malik said, "It is not halal for a man to have intercourse with his wife while he is in itikaf, nor for him to take pleasure in her by kissing her, or whatever. However, I have not heard anyone disapproving of a man, or woman, in itikaf getting married as long as there is no physical relationship. Marriage is not disapproved of for someone fasting."
"There is, however, a distinction between the marriage of someone in itikaf and that of someone who is muhrim, in that some one who is muhrim can eat, drink, visit the sick and attend funerals, but cannot put on perfume, whilst a man or woman in itikaf can put on oil and perfume and groom their hair, but cannot attend funerals or pray over the dead or visit the sick. Thus their situations with regard to marriage are different."
"This is the sunna as it has come down to us regarding marriage for those who are muhrim, doing itikaf, or fasting.
