Say 'Al Hamdu Lillahi' when one sneeze . Respond 'Yarhamuk Allah' to the one who has just sneeze . Reply 'yahdikummullahu wa yuslihi balakumm' after responding .

This hadith is about the etiquette that Muslims must follow when someone sneezes. According to this hadith, when someone sneezes they should say “Al-Hamdu Lillah” which means “praise be to God”. The other person must then respond with “Yarhamuk-Allah” which means “may God have mercy on you”. The person who has just sneezed must then reply with “Yahdikum-ullah wa yuslihu balakum” which means “may God guide you and render sound your state of affairs”. This is an important part of Islamic etiquette as it shows respect for God and for one another. It also serves as a reminder that we are all connected through our faith in God and His mercy upon us all.
