Musannaf Ibn Abi Shayba 3:6443

Muhammad ibn Abi ‘Adi narrated to us, from Ibn ‘Awn, who said: Muhammad [ibn Sirin] was asked about the one who recites from here and from here [i.e., skipping around in the Quran] in order to avoid [a difficult passage]. He said: He commits a great sin while he does not perceive it.
