As Salam alaikum wa rahmatullah wa barakatu my beloved beautiful Brothers and Sisters, Please whenever you sneez than say Alhamdulillah and your Brother who heard that should respond with "Yarḥamuk Allāh and then you who sneezed should respond with Yahdikum Allah wa yuslih balakum. The natural act of sneezing is a mercy and grace of Allah Azza Wa Jal. It relieves us from discomfort, and we should thank Allah azza wa jal for it. When you say ”Alhamdulillah” when you sneeze, you're reviving a sunnah! There's another sunnah to revive while sneezing; it's covering your mouth as the Prophet s.a.w.s. did. Share it so you may gain Hasanat InshaaAllah Ta'ala. May Allah Azza Wa Jal guide and bless you all always and grant you all Jannat Al Fridaous Amin Ya Rabil Alamin wa alaikum salam Wa rahmatullah Wa barakatu
