Is it better for one who enters a gathering to shake hands with them?

Question:
Some people, when they enter the gathering and greet, sit down and do not shake hands?

Answer:
He has the choice. If he shakes hands, there is no harm, and if he greets and sits, there is no harm. The matter is broad.
From the perspective of care; if he shakes hands out of care, that is good. But if it burdens the people, or if he sees that it burdens them and there are many of them, sitting down may be more comfortable for the people so as not to burden them. And if he shakes hands, it is not blameworthy; because the Companions used to shake hands when they met.
Q: What is recommended to wipe away sins and mistakes?
The Shaykh: It is recommended upon meeting. The Companions used to shake hands when they met and when they met the Prophet (peace and blessings be upon him). But if the gathering has a large number of people, it may tire them or tire himself, or occupy them with what is more important. One should consider the meaning. The one entering should consider; it may be that not shaking hands with them is difficult for them, and they see it as rudeness. He may see that shaking hands harms them or is difficult for them. The one entering should consider the matters, not be heedless, and not lack discernment. He should consider.
