Musannaf Ibn Abi Shaybah 2285 — Travellers: do they call the adhan

Abd al-Malik said: Ata was asked whether travellers should give both the adhan and the iqamah. He said: "The iqamah suffices for them, unless the travellers are scattered in different places; then, in order to gather them, both the adhan and the iqamah are to be given."
