عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا عَطَسَ أَحَدُكُمْ فَلْيَقُلْ الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ وَلْيَقُلْ مَنْ حَوْلَهُ يَرْحَمُكَ اللَّهُ وَلْيَقُلْ هُوَ يَهْدِيكُمُ اللَّهُ وَيُصْلِحُ بَالَكُمْ
Sayyiduna Ali (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: When any of you sneezes, he should say: "Alhamdulillahi Rabbil 'Alamin" (All praise is due to Allah, Lord of the worlds), and those around him should say: "Yarhamukallah" (May Allah have mercy on you), and then the one who sneezed should say: "Yahdikumullah wa yuslihu balakum" (May Allah guide you and set your affairs right).
