Saying "Qad qamat al-salah" twice and the phrases before it once

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that Sayyiduna Bilal (may Allah be pleased with him) was ordered to say the adhan in pairs and the iqamah once each, except that 'Qad qamat al-salah' (The prayer has indeed been established) should be said twice.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that Sayyiduna Bilal (may Allah be pleased with him) was ordered "to say the adhan in pairs and the iqamah once each, except that 'Qad qamat al-salah' should be said twice."

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that in the time of the Prophet (peace and blessings be upon him) the adhan was twice each and the iqamah once each; when the muezzin says 'Qad qamat al-salah' (The prayer has been established), he should say it twice.

Abu al-Muthanna said: I heard Sayyiduna Ibn Umar (may Allah be pleased with them both) say: "In the time of the Prophet (peace and blessings be upon him) the adhan was twice each and the iqamah once each; when he said 'Qad qamat al-salah' (The prayer has been established), he would say it twice. When any of us heard the iqamah, he would perform ablution and then come out."

Ibrahim bin Abd al-Aziz bin Abd al-Malik bin Abi Mahdhurah (may Allah have mercy on him) said: I found my father and my grandfather giving this same adhan that I give and saying this same iqamah, and they used to say that the Prophet (peace and blessings be upon him) taught this to Abu Mahdhurah (may Allah be pleased with him). He mentioned the adhan, then said: And the iqamah once each: '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).

Ibrahim bin Abd al-Aziz bin Abd al-Malik bin Abi Mahdhurah (may Allah have mercy on him) said: I heard my father and my grandfather, both of them narrating from Sayyiduna Abu Mahdhurah (may Allah be pleased with him), that he used to give the adhan for the Prophet (peace and blessings be upon him); he would say the iqamah once each, except 'Qad qamat al-salah', which he said twice.
