Q 3: My brothers and I are married and have many children.
Is it permissible for me to shake hands with my sisters-in-law
and for my brothers to shake hands with my wife, as I consider my sisters-in-law to be like my full blood sisters and trust them fully?
A:
It is not permissible for you to shake hands with any of your sisters-in-law nor is any of your brothers permitted to shake hands with your wife. May Allah grant us success. May peace and blessings be upon our Prophet, his family, and Companions.
