Mukhtasar Bukhari (Abridged) 987 — Some did not consider whispers

Narrated from Ummul Momineen Aisha Siddiqa (may Allah be pleased with her): Some people said, "O Messenger of Allah! Some men bring us meat (to sell), and we do not know whether they have recited Bismillah over it or not." So the Prophet (peace be upon him) said: "Recite Bismillah over it yourselves and eat."
