The Sunnah of the Prophet is fixed
The sneezer gloated
On the authority of Abu Hurairah, may God be pleased with him
On the authority of the Prophet, may God bless him and grant him peace, he said
If one of you sneezes, let him say, “Praise be to God.”
Let his brother or friend tell him
May God have mercy on you
If he says to him, may God have mercy on you
Let him say, “May God guide you and set your mind at ease.”
