Jami` at-Tirmidhi Book 43, Hadith 7
This is how Shu'bah reported this Hadith from IbnAbi Laila, and he said: "From Abu Ayyub from the Prophet (ﷺ)." Ibn Abi Laila was confused in this narration, sometimes he would say: "From Abu Ayyub from the Prophet (ﷺ)" and sometimes he would say: "From 'Ali from the Prophet (ﷺ)" similarly in meaning.
that the Messenger of Allah (ﷺ) said: "When one of you sneezes let him say: 'Al-Hamdulillahi 'Ala Kulli Hal (All praise is due to Allah in every circumstance).' And let the one replying to him say: "Yarhamukallah (May Allah have mercy upon you).' And let him say to him: 'Yahdikumullah Wa Yuslihu Balakum (May Allah guide you and rectify your affairs).'"
(Another chain) from 'Ali from the Prophet (ﷺ) with similar meaning.
