Repeating after the Mu'adhin and making Du`a' after Adhan and Iqamah

A: It is proper to say, 'La hawla wa-la quwwata illa billah (There is neither might nor power except with Allah)' after the Mu'adhin says, 'Come to Salah; Come to success' and not to repeat them. This is based on the apparent meaning of the Hadith reported on the authority of `Umar (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: When the Mu'adhin says: Allah is the Greatest, Allah is the Greatest, you should respond in this way: (Part No. 6; Page No. 85) Allah is the Greatest, Allah is the Greatest; (and when the Mu'adhin) says: I testify that there is none worthy of worship (in truth) but Allah, one should respond: I testify that there is none worthy of worship (in truth) but Allah, and when he says: I testify that Muhammad is the Messenger of Allah, one should respond: I testify that Muhammad is Allah's Messenger. When he (the Mu'adhin) says: Come to prayer, one should respond: There is no might and no power except with Allah. When he (the Mu'adhin) says: Come to success, one should respond: There is no might and no power except with Allah, and when he (the Mu'adhin) says: Allah is the Greatest, Allah is the Greatest, then respond: Allah is the Greatest, Allah is the Greatest. When he (the Mu'adhin) says: There is none worthy of worship (in truth) but Allah, and he who makes a response from the heart: there is none worthy of worship (in truth) but Allah, will enter Paradise. The Hadith apparently indicates that one should not repeat the Mu'adhin's statements, 'Come to Salah; Come to success.' Rather, one should say, 'La hawla wa-la quwwata illa billah (There is neither might nor power except with Allah).' This is a specification of the general meaning of the Hadith reported on the authority of Abu Sa`id and other Hadith to the effect that one should repeat what the Mu'adhin says.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
