Musannaf Ibn Abi Shayba 3:1326

Waki’ narrated to us, he said: Al-A’mash narrated to us, from Ibrahim, from Alqama, that he used to recite in the Fajr [prayer] in the first rak’ah: *Ha-Mim Al-Dukhan*, *Al-Tur*, and *Al-Hashr*. And he used to recite in the second [rak’ah]: the end of *Al-Baqarah*, the end of *Al-Imran*, and a short surah.
