The tradition mentioned above (No. 5013) has also been mentioned by Salim ibn Ubayd al-Ashja'i to the same effect from the Prophet (ﷺ) through a different chain of narrators.
Sunan Abi Dawud Book 43, Hadith 260
← Previous Hadith Hilal ibn Yasar said: We were with Salim ibn Ubayd when a man from among the people sneezed and said: Peace be upon you.

Salim said: And upon you and your mother. Later he said: Perhaps you found something (annoying) in what I said to you.

He said: I wished you would not mention my mother with good or evil. He said: I have just said to you what the Messenger of Allah (ﷺ) said. We were in the presence of the Messenger of Allah (ﷺ) when a man from among the people sneezed, saying: Peace be upon you!

The Messenger of Allah (ﷺ) said: And upon you and your mother. He then said: When one of you sneezes, he should praise Allah. He further mentioned some attributes (of Allah), saying: The one who is with him should say to him: Allah have mercy on you, and he should reply to them: Allah forgive us and you.

Sunan Abi Dawud Book 43, Hadith 259 Next Hadith → When one of you sneezes, he should say: "Praise be to Allah in every circumstance," and his brother or his companion should say: "May Allah have mercy on you!" And he should then reply: "May Allah guide you and set right your affairs."
