Bayhaqi 1964 — Those who held that "Qad qamat al-salah" is said once

Sa'id bin al-Musayyib (may Allah have mercy on him), relating the story of the adhan, said that the first person who was shown it in his sleep was a man of the Ansar from Banu al-Harith bin al-Khazraj named Abdullah bin Zayd (may Allah be pleased with him). He said: I was asleep when suddenly I saw a man walking with a bell (naqus) in his hand. I said: "O servant of Allah, will you sell this bell?" He said: "What do you want with it?" I said: "I want to take it to call people to prayer." He said: "Shall I not tell you of something better than that? Say:"
'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, 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 should 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, 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, Allah is the Greatest, Allah is the Greatest, there is no god but Allah). Ibn al-Musayyib (may Allah have mercy on him) said: Abdullah bin Zayd (may Allah be pleased with him) woke up, gathered his clothes about him and came to the Messenger of Allah (peace and blessings be upon him); he had been shown the adhan in his dream. He said: Umar bin al-Khattab (may Allah be pleased with him) was also shown something like it, and he came and informed the Messenger of Allah (peace and blessings be upon him) of what he had been shown. The first of the two (may Allah be pleased with them both) to reach the Messenger of Allah (peace and blessings be upon him) with the dream was Abdullah bin Zayd al-Ansari (may Allah be pleased with him). He found that the Messenger of Allah (peace and blessings be upon him) had already ordered the call to prayer, and he (peace and blessings be upon him) ordered Bilal (may Allah be pleased with him) to give the adhan; he first gave the adhan, then the iqamah.
