Musannaf Ibn Abi Shaybah 8381 — Those who used to shorten the prayer

Abu Ishaq said: We were in Sijistan, and I asked Salamah bin Suhayb about the prayer. He said: Pray two rak'ahs at a time until you return to your family. Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) also used to say the same.
