Translation

"The Messenger of Allah (ﷺ) said: 'When one of you sneezes, let him say: Alhamdulillah (All praise is for Allah). And let his brother or companion say to him: Yarhamuk Allah (May Allah have mercy on you). And when he says to him: Yarhamuk Allah, let the one who sneezed reply: Yahdikum Allah wa yuslihu balakum (May Allah guide you and set your affairs right).'" .
