AHMAD 8631:
from Abū Hurayrah —
[Machine] The Prophet ﷺ said, "When one of you sneezes, let them say, 'Alhamdulillah' (Praise be to Allah). And when they say, 'Alhamdulillah,' let their brother say to them, 'Yarhamukallah' (May Allah have mercy on you). And when it is said to them, 'Yarhamukallah,' let them say, 'Yahdikumullah wa yuslih balakum' (May Allah guide you and rectify your affairs)."

عن ابو هريره —
أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا عَطَسَ أَحَدُكُمْ فَلْيَقُلْ الْحَمْدُ لِلَّهِ فَإِذَا قَالَ الْحَمْدُ لِلَّهِ قَالَ لَهُ أَخُوهُ يَرْحَمُكَ اللهُ فَإِذَا قِيلَ لَهُ يَرْحَمُكَ اللهُ فَلْيَقُلْ يَهْدِيكُمُ اللهُ وَيُصْلِحُ بَالَكُمْ
