Musannaf Ibn Abi Shaybah 6415 — Combining two prayers on a rainy night

Hisham bin Urwah said: Aban bin Uthman used to combine the Maghrib and Isha prayers on a rainy night, and I saw Urwah bin al-Zubayr, Sa'id bin al-Musayyib, Abu Bakr bin Abd al-Rahman and Abu Salamah bin Abd al-Rahman praying with him. None of them objected to this practice.
