Musannaf Ibn Abi Shaybah 2288 — Travellers: do they call the adhan

Al-Harith said: We were with Sayyiduna Abu Musa (may Allah be pleased with him) at Ayn al-Tamr, in the post-house (dar al-barid). He gave the adhan and then said the iqamah. We asked: "What if you were out in the open wilderness?" He said: "This place and that are the same."
