ʿIf one of you sneezes, let him say: Praise be to Allah in all situations. Let others say to him; May Allah have mercy on you. And let him say May Allah guide you and rectify your condition.” I said to him: Is it from Abu Ayyoob? He said: ʿAli ؓ . (Using translation from Aḥmad 995)
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ إِذَا عَطَسَ أَحَدُكُمْ فَلْيَقُلِ الْحَمْدُ لِلَّهِ عَلَى كُلِّ حَالٍ وَلْيَقُلِ الَّذِي يَرُدُّ عَلَيْهِ يَرْحَمُكَ اللهُ وَلْيَقُلْ هُوَ يَهْدِيكَ اللهُ وَيُصْلِحُ بَالَكَ قَالَ حَجَّاجٌ يَهْدِيكُمُ اللهُ وَيُصْلِحُ بَالَكُمْ
