Musnad Ahmad 1153:272

Yahya narrated to us, from Zakariya, from 'Amir, from Abu Salamah, from 'Aishah, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, Jibril (peace be upon him) sends his greetings to you." She said: "And upon him be peace and the mercy of Allah."
