What is the ruling on embracing and shaking hands when meeting?

The Shaykh: It is not considered unlikely here; it is permissible for us. Rather, we say: because of the prohibition of embracing, and the prohibition is the default rule, from which exceptions are made only where permissibility is established. We will not find anything other than these two instances: the first is when a traveler arrives, and the second is when longing increases. This is what I have gathered over a long period of study, research, and verification.
