Musannaf Ibn Abi Shayba 19:241

Abu Bakr narrated to us, he said: Ibn Mahdi narrated to us, from Hammad ibn Salamah, from Qatadah, from Sulayman ibn Yasar, ‘Ata’, and al-Hasan, regarding a man who says to his wife, "I did not find you a virgin." They said: "Virginity is removed by the *naytah* (a heavy fall or a jump) and the *laytah* (a slip or a fall)."
