Is it permissible for someone who sneezes while the imam is delivering the Friday sermon to praise Allah? And is it permissible for the one who hears it to respond to him?

The questioner : One person sneezed, my Shaykh, while the imam was delivering the Friday sermon. What must I do? He said, "Praise be to Allah."

The Shaykh : Are you asking about the one who sneezes, or about the one who hears the sneeze?

The questioner : The one who hears the sneeze.

The Shaykh : He does nothing.

The questioner : Does he not say to him, "May Allah have mercy on you"?

The Shaykh : No.

The questioner : The one who sneezes.

The Shaykh : Yes.

The questioner : And the one who sneezes.

The Shaykh : He praises Allah to himself.

The questioner : Likewise in the prayer.

The Shaykh : In the prayer, there is a point to consider.

The questioner : The sending of blessings upon the Prophet.

The Shaykh : Indeed, the sending of blessings upon the Prophet (peace and blessings be upon him) has broad scope and no limits. As for the sneeze, its response is specific to a moment. Hello, welcome, and peace be upon you. How are you? Do you have something? Give it to me, please. I will send it to Abu Muhammad.
The student : ... .

The Shaykh : If Allah wills.
The student: Peace be upon you.

The Shaykh : Peace be upon you, and Allah's mercy and blessings. The response to the sneeze is immediate, and it is obligatory.
