Musnad Ahmad 1012:50

Muhammad ibn Ja‘far narrated to us, Sa‘id narrated to us, from Qatadah, from al-Hasan, from Hattan ibn ‘Abd Allah al-Raqashi, from Ibn al-Samit, who said: When the revelation would descend upon the Messenger of Allah (may Allah bless him and grant him peace), he would be affected by distress because of that, and his face would change color. Then, one day, Allah sent down [the revelation], and when it was lifted from him, he said: "Take from me: Allah has indeed made a way for them. The previously married [person] with the previously married [person], and the virgin with the virgin. The previously married [person receives] one hundred lashes and stoning with stones, and the virgin [receives] one hundred lashes and then banishment for a year."
