It is narrated from Sayyiduna Abu Mahdhurah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) taught me this adhan: "'Allahu akbar, Allahu akbar, Allahu akbar, Allahu akbar' (Allah is the Greatest, Allah is the Greatest, Allah is the Greatest, Allah is the Greatest), 'Ash-hadu an la ilaha illallah, ash-hadu an la ilaha illallah' (I bear witness that there is no god but Allah, I bear witness that there is no god but Allah), 'Ash-hadu anna Muhammadan rasulullah, ash-hadu anna Muhammadan rasulullah' (I bear witness that Muhammad is the Messenger of Allah, I bear witness that Muhammad is the Messenger of Allah); then he would say again: 'Ash-hadu an la ilaha illallah, ash-hadu an la ilaha illallah' (I bear witness that there is no god but Allah, I bear witness that there is no god but Allah), 'Ash-hadu anna Muhammadan rasulullah, ash-hadu anna Muhammadan rasulullah' (I bear witness that Muhammad is the Messenger of Allah, I bear witness that Muhammad is the Messenger of Allah); 'Hayya 'alas-salah' (Come to the prayer) twice and 'Hayya 'alal-falah' (Come to success) twice; 'Allahu akbar, Allahu akbar' (Allah is the Greatest, Allah is the Greatest), 'La ilaha illallah' (There is no god but Allah)."
