Chapter: The Adhan While Traveling
• Ahmad was asked about the adhan while traveling, and he said: "Yes." It was said: "What of the hadith of Malik ibn al-Huwayrith? He said: The Prophet (peace and blessings of Allah be upon him) said to me and a companion of mine: 'When you both travel, call the adhan, then perform the iqamah, then let the older of you lead you in prayer.'" He replied: "Yes."
Ahmad said—regarding the interpretation of "the older of you": "It means they were close to each other in [their knowledge of] the recitation."

He said: "And we were close to each other," meaning: in knowledge.
