What is the ruling on shaking hands with the guests to congratulate the groom and his bride?

Question:
It is stated that when a person gets married, on the day of the wedding or the night of the wedding, he sits in a chair with his wife next to him among the guests. People come to congratulate him, both men and women, and they shake his hand and shake his wife's hand. Is this permissible or not?

Answer:
This is one of the bad customs. If it involves shaking hands between foreign men and a woman who is not a mahram, then this is forbidden, as mentioned previously. Likewise, the groom entering among the women and sitting next to his wife in front of the women is also an abomination, and it involves fitnah (trial, discord or temptation). He may see among the women present what he is not permitted to look at, or they may be tempted by him. Similarly, the reverse is the case: bringing the bride to the gathering of men, and her sitting in front of her husband while men shake her hand. All of these are abominations and forbidden. The obligatory thing is to maintain privacy in such cases, by having the groom enter his bride in a place prepared for that purpose and free of people. May Allah bless you.
