The Ruling on Giving a Gift on the Occasion of the Wedding Anniversary
Question :
Is it permissible for a husband to give a gift to his wife on the occasion of their wedding anniversary every year, in order to renew the affection and love between them. Bear in mind, that the remembrance is confined only to giving a gift, and the spouses do not hold a celebration on this occasion?
Answer:
It is my opinion that this door be closed, because this year it will be a gift and next year it might be a celebration. Also, simply marking this occasion by giving a gift is making it into an Eid. An 'Eid is anything which is repeated or returns (annually), and affection should not be renewed every year. Rather it should be renewed at all times: Whenever the wife sees something from the husband which pleases her, and every time the husband sees something from the wife which pleases him, their affection and love will be renewed.
