Is it permissible for the husband to kiss his wife's head at the marriage contract ceremony, or is that considered a temptation for the women present?

A groom kissing his bride on her head in front of people is not considered a breach of murūʾah (chivalry/propriety) by some scholars; rather, it is among the permissible acts. However, it is prohibited if it causes fitnah (temptation or discord) for those present, both men and women, because Islamic law blocks the door to fitnah and forbids everything that leads to it. It is important to note that it is not permissible for the husband to enter among the women at a wedding celebration, as this is a practice that violates Islamic law.
