Musannaf Ibn Abi Shaybah 3755 — A surah divided over two rakahs

Amr bin Murrah said: I prayed Fajr behind Sa'id bin Jubayr. In the first rak'ah he began reciting Surah Ha Mim al-Mu'min. When he reached {in the evening and the morning} [Ghafir: 55], he bowed; then in the second rak'ah he recited the rest of the surah, then bowed, and he did not recite the Qunut supplication in Fajr.
