When is it permissible to miss the congregational prayer due to a lack of khushu' (humility), such as extreme heat or the like?

The questioner : Anything that prevents khushu' in prayer excuses a person from missing the congregation. Even if, for example, he is in a place with a very disturbing smell, and now a person finds that some people cannot bear the smell. If he goes to pray, he suffers, and perhaps he might faint from the smell, and he says, "I am starting to feel restless and agitated." Is he excused from missing the congregation or not?

The Shaykh : The answer is yes, he is excused, because we know that the Messenger (peace and blessings be upon him), when he said, "Do not pray while you are in a state of hunger or while you are straining to relieve yourself," what is the purpose of this? Why?

The questioner : A person.

The Shaykh : So that a person comes to his prayer in a state where his heart is not distracted. Therefore, whatever distracts the heart, a person is excused from missing the Friday prayer and the congregation.
