The Ruling on Responding to a Disbeliever’s Sneeze and the Formulas of Praise and Response

Question:
If a disbeliever sneezes?

Answer:
If he sneezes and praises Allah, one says: “May Allah guide you,” just as the Jews used to sneeze in the presence of the Prophet (peace and blessings be upon him), and when they praised Allah, he would say: “May Allah guide you.”
Q: Is this from the chapter of supplication?
A: It is from the chapter of supplicating for them for guidance.
Q: The one who says that there are three formulas for responding to the sneezer: the first is when he says: “Praise be to Allah,” the responder replies by saying: “May Allah guide you and rectify your condition”?
A: “May Allah have mercy on you.”
Q: Yes, the second: if he sneezes and says: “Praise be to Allah, Lord of the worlds,” then when the responder replies, he says: “May Allah forgive us and you”?
A: No, it has no basis. In all cases, he praises Allah, and the responder says: “May Allah have mercy on you,” and he says: “May Allah guide you and rectify your condition.”
Q: Meaning: did not hadiths come mentioning, for example: “Praise be to Allah in all circumstances”?
A: These are types of praise. However he praises Allah, one says to him: “May Allah have mercy on you.”
Q: Is it established from the Messenger of Allah that if he sneezed more than three times, he would say to him: “May Allah heal you”?
A: Nothing authentic has come regarding this. He only said: This one is congested. But nothing prevents responding to him if he praises Allah... and if one supplicates for his healing, there is no harm.
