If a person
    sneezes during his prayer
Question

                If a person sneezes during his prayer, should he say ‘ Al-hamdu Lillaah  (Praise be to Allaah)’? If he says it, should those who hear him say, ‘ Yarhamuk Allaah (may Allaah have mercy on
      you)’?
Praise be to Allah.Yes, he should say that, and anyone
    who hears him and is not himself praying should say ‘Yarhamuk Allaah’ to
    him.
