It is narrated from Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "The one who sneezes should say: «اَلْحَمْدُ لِلّٰهِ عَلَى كُلِّ حَالٍ» (All praise is due to Allah in every circumstance), and the one who hears should reply: «يَرْحَمُكُمُ اللّٰهُ» (May Allah have mercy on you), then the one who sneezed should say: «يَهْدِيْكُمُ اللّٰھُ وَيُصْلِحُ بَالَكُمْ» meaning, May Allah guide you and rectify your condition."
