Can I pray at home if there is severe dust–Al-Allaamah Saaleh Al-Fawzaan

O virtuous Shaikh, may Allaah grant you success. If there is severe dust, is it permissible for me to pray at home out of fear for my health?

Yes; if you are affected by the dust—clearly affected; then pray at home. This is an excuse. Yes.
