Al-Muwatta de Malik, 234

On rapporta à Malek, qu'un homme éternua un jour de Vendredi, alors que l'imam faisait son prône. Un autre qui se trouvait à côté de lui dit: «que Allah te fasse Miséricorde». Demandant l'avis de Sa'id Ibn Al-Moussaiab à ce sujet, il l'interdit de le refaire, en lui disant: «ne le recommence pas»

Yahya related to me from Malik that he had heard that a man sneezed on the day of jumua while the imam was giving the khutba, and a man by his side asked Allah to bless him. Said ibn al Musayyab was asked about it and he forbade the man to do what he had done and said, "Don't do it again
