Abu Dawud Book 2, Hadith Number 772.

Chapter : Not known.

Narated By Rifa’ah ibn Rafi’ : I offered prayer behind the Apostle of Allah (PBUH). Rifa’ah sneezed. The narrator Qutaybah did not mention the name Rifa’ah (but he said: I sneezed). So I said: Praise be to Allah, praise much, good and blessed therein, blessed thereupon, as our Lord likes and is pleased. When the Apostle of Allah (PBUH) finished his prayer, he turned and said: Who was the speaker in prayer? He then narrated the rest of the tradition like that of Malik and completed it.
