On sneezing
Sahihفَلْيَقُلِ الْحَمْدُ لِلَّهِ. وَلْيَقُلْ لَهُ أَخُوهُ أَوْ صَاحِبُهُ يَرْحَمُكَ اللَّهُ. فَإِذَا قَالَ لَهُ يَرْحَمُكَ اللَّهُ. فَلْيَقُلْ يَهْدِيكُمُ اللَّهُ وَيُصْلِحُ بَالَكُمْ
Whoever sneezes says al-ḥamdu lillāh (praise be to Allah). His brother or companion answers yarḥamukAllāh (may Allah have mercy on you), and he replies yahdīkumullāhu wa yuṣliḥu bālakum (may Allah guide you and set your affairs right).
