Sayyidah Azzah bint Iyad bin Abi Qirsafah (may Allah be pleased with her) narrates: The Romans took a son of Sayyiduna Abu Qirsafah (may Allah be pleased with him) captive. So at the time of every prayer, Sayyiduna Abu Qirsafah (may Allah be pleased with him) would stand on the walls of the city of Asqalan and call out in a loud voice: "O so-and-so! The time of prayer has come." And his son would hear his voice, even though he was in the land of the Romans.
Al-Tabarani recorded it, and its narrators are thiqat (trustworthy).
