Musannaf Ibn Abi Shaybah 14323 — A man who fasts during tamattu

Ata, Ibn Sirin and al-Hasan said: If you have fasted (for Tamattu') in Hajj, then you find a sacrificial animal before finishing your fasts, offer the expiation; and if you find it after your fasts are complete, then no expiation is due from you.
