The Jews used to try to sneezes in the presence of the Prophet ﷺ hoping that he would say to them: "Allah have mercy on you!" but he would say: May Allah guide you and grant you well-being! (Using translation from Abū Dāʾūd 5038)
كَانَتْ يَهُودُ يَأْتُونَ رَسُولَ اللهِ ﷺ فَيَتَعَاطَسُونَ رَجَاءَ أَنْ يَقُولَ يَرْحَمُكُمُ اللهُ فَكَانَ يَقُولُ «يَهْدِيكُمُ اللهُ وَيُصْلِحُ بَالَكُمْ»
