Musannaf Ibn Abi Shayba 3:6441

Abu Bakr narrated to us, he said: 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 this surah. He said: "I passed by you, O Bilal, while you were reciting from this surah and from this 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 order."
