Today, I met with a man and did musafaha with one hand as I had a bag in another hand.
He told me: "Put down your bags on the floor and do musafaha with two hands."
I told him: "Is not it permissible to do musafaha with one hand?"
He told me: "There is no evidence in hadith to do musafaha with one hand."
I told him: "As far I know, it is allowed. Do you have any evidence of doing musafaha with two hands?"
He told me: "Yes. In the time of Prophet (SM ), If anybody comes to Prophet (SM) and wants to do musafaha with one hand, he denies him. If you want to see my evidence, please bring your evidence also."
Now, I am in need of evidence of doing musafaha with one hand.
If it is not allowed, tell me and prove by hadith.
Otherwise help me by giving evidence for opposite.
