The Jews used to sneeze in the presence of the Prophet ﷺ hoping that he would say: 'Yarhamukumullah (May Allah have mercy upon you).' So he said: 'Yahdikumullahu Wa Yuslihu Balakum (May Allah guide you and rectify your affairs).'"
كَانَ الْيَهُودُ يَتَعَاطَسُونَ عِنْدَ النَّبِيِّ ﷺ يَرْجُونَ أَنْ يَقُولَ لَهُمْ يَرْحَمُكُمُ اللَّهُ فَيَقُولُ يَهْدِيكُمُ اللَّهُ وَيُصْلِحُ بَالَكُمْ وَفِي الْبَابِ عَنْ عَلِيٍّ وَأَبِي أَيُّوبَ وَسَالِمِ بْنِ عُبَيْدٍ وَعَبْدِ اللَّهِ بْنِ جَعْفَرٍ وَأَبِي هُرَيْرَةَ
