Musannaf Ibn Abi Shayba 37:185

'Abd al-Wahhab al-Thaqafi narrated to us, from Ayyub, from Muhammad, that a man from the companions of the Prophet (may Allah bless him and grant him peace) said: "The tribulation (fitna) did not reach anyone among us, such that if I wished to say something about him, I would have said it, except for 'Abd Allah ibn 'Umar."
