Musannaf Ibn Abi Shayba 22:348

Hatim ibn Isma'il narrated to us, from 'Abd al-Rahman ibn Harmala, from Sa'id ibn al-Musayyib, who said: The Messenger of Allah (may Allah bless him and grant him peace) passed by Bilal while he was reciting from this surah and from that surah. He said, "May my father be sacrificed for you, O Messenger of Allah, I wanted to mix the good with the good." He said, "Recite the surah in its proper order."
