Bayhaqi 1965 — Those who held that "Qad qamat al-salah" is said once

It is narrated from Sayyiduna Abdullah bin Zayd bin Abd Rabbih (may Allah be pleased with him): When the Messenger of Allah (peace and blessings be upon him) had resolved to have the bell (naqus) struck to gather the people for prayer, while he (peace and blessings be upon him) disliked it because it resembled the Christians, one night, while I was asleep, a man came circling around me in a dream. He wore two green garments and had a bell in his hand. I said to him: "O servant of Allah, will you sell this bell?" He said: "What will you do with it?" I said: "I will call people to prayer with it." He said: "Shall I not tell you of something better than that?" I said: "Certainly!" He said: "Say: 'Allahu akbar, Allahu akbar, Allahu akbar, Allahu akbar, ashhadu an la ilaha illallah, ashhadu an la ilaha illallah, ashhadu anna Muhammadan rasulullah, ashhadu anna Muhammadan rasulullah, hayya 'ala al-salah, hayya 'ala al-salah, hayya 'ala al-falah, hayya 'ala al-falah, Allahu akbar, Allahu akbar, la ilaha illallah' (Allah is the Greatest, Allah is the Greatest, Allah is the Greatest, Allah is the Greatest, I bear witness that there is no god but Allah, I bear witness that there is no god but Allah, I bear witness that Muhammad is the Messenger of Allah, I bear witness that Muhammad is the Messenger of Allah, come to prayer, come to prayer, come to success, come to success, Allah is the Greatest, Allah is the Greatest, there is no god but Allah)." Then he stayed a little while, then said: "When you say the iqamah, say: 'Allahu akbar, Allahu akbar, ashhadu an la ilaha illallah, ashhadu anna Muhammadan rasulullah, hayya 'ala al-salah, hayya 'ala al-falah, qad qamat al-salah, qad qamat al-salah, Allahu akbar, Allahu akbar, la ilaha illallah' (Allah is the Greatest, Allah is the Greatest, I bear witness that there is no god but Allah, I bear witness that Muhammad is the Messenger of Allah, come to prayer, come to success, the prayer has been established, the prayer has been established, Allah is the Greatest, Allah is the Greatest, there is no god but Allah)." In the morning I came to the Messenger of Allah (peace and blessings be upon him) and told him what I had seen. The Messenger of Allah (peace and blessings be upon him) said: "This is a true dream, if Allah Almighty wills." Then he (peace and blessings be upon him) ordered the adhan, and Sayyiduna Bilal (may Allah be pleased with him), the freed slave of Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him), used to give the adhan.
