The Prophet ﷺ said, "When one of you sneezes, let him say, 'Praise be to Allah in every state.' His brother or companion should respond, 'May Allah have mercy on you.' Then he should reply, 'May Allah guide you and set your affairs right.'"
حدثنا موسى بن إسمعيل حدثنا عبد العزيز بن عبد الله بن أبي سلمة عن عبد الله بن دينار عن أبي صالح
عن النبي ﷺ قال إذا عطس أحدكم فليقل الحمد لله على كل حال وليقل أخوه أو صاحبه يرحمك الله ويقول هو يهديكم الله ويصلح بالكم
