Can you provide the text of the hadith mentioned in Ibn Hajar's "Fath al-Bari" (Vol. 10, p. 735, chapter: Praising Allah for Sneezing), attributed to al-Tabari's "Tahdhib al-Athar," which states: "Umm Salamah narrated: A man sneezed in the presence of the Prophet (peace be upon him) and said: 'Alhamdulillah (Praise be to Allah).' The Prophet (peace be upon him) said to him: 'Yarhamukallah (May Allah have mercy on you).' Then another man sneezed and said: 'Alhamdulillahi Rabbil-Alamin Hamdan Tayyiban Kathiran Mubarakan Fihi (Praise be to Allah, Lord of the worlds, a good, abundant, blessed praise).' So, he [the Prophet] said: 'This one surpassed that one by nineteen degrees'?"?

The dhikr (remembrance) mentioned is the text of the hadith, and it has been reported in multiple sources such as "Kanz al-Ummal" and "Sharh al-Tirmidhi". Ibn Hajar and Al-Mubarakfuri affirmed its authenticity. Its permissibility upon sneezing has been established by the Prophet's (peace be upon him) approval of someone who sneezed during prayer, as narrated in the hadith of Rifaa ibn Rafi, which Al-Hakim authenticated and Al-Dhahabi silently concurred with, and Al-Albani authenticated. In this hadith, Rifaa sneezed during prayer and said: "Praise be to Allah, much good, pure, blessed praise in it, blessed upon it, as our Lord deserves and is pleased with." The Prophet (peace be upon him) approved his saying and said: "By Him in Whose Hand is my soul, indeed more than thirty angels rushed to it, vying as to which of them would take it up."
