Saying 'Allâh and His angels send Salah on the Prophet Muhammad' after the Adhan

Q: Allah (Exalted be He) says: Allâh sends His Salât (Graces, Honours, Blessings, Mercy) on the Prophet (Muhammad صلى الله عليه وسلم), and also His angels (ask Allâh to bless and forgive him). O you who believe! Send your Salât on (ask Allâh to bless) him (Muhammad صلى الله عليه وسلم), and (you should) greet (salute) him with the Islâmic way of greeting (salutation i.e. As-Salâmu ‘Alaikum ). Is it permissible for a Mu'adhin (caller to Prayer) to recite this Ayah (Qur'anic verse) after the Adhan (call to Prayer)? Is it a Sunnah (whatever is reported from the Prophet), a desirable act, or a Bid`ah (innovation in religion)? Is it permissible for a Mu'adhin to say before the Iqamah (call to start the Prayer): "O Allah! Protect us from the shame of the world and the torment of the Hereafter, O Generous. O Allah, be merciful to me as You were with all the Companions of the Messenger of Allah"?

A: It is prescribed for everyone who hears the Adhan to repeat what the Mu'adhin says, except when reaching the phrases "Hay `ala-al-Salah" and "Hay `ala-al-Falah (come to Prayer, come to success)," they should say "La Hawla wala Quwwata illa Billah (there is neither might nor power except with Allah)." After finishing the Adhan, they should send peace and blessings upon the Prophet (peace be upon him) without pronouncing it loudly. Afterwards, they should say: O Allah! Lord of this most perfect call (to Prayer) and of the Prayer that is to be established, grant our master, Muhammad, Al-Wasilah (the most superior degree in Paradise) and a rank of distinction, and resurrect him to the lauded position that You promised him. It was narrated on the authority of `Abdullah ibn (Part No. 5; Page No. 79) `Amr ibn Al-`As (may Allah be pleased with him and his father) that he heard the Prophet (peace be upon him) saying: Whenever you hear the Mu'adhin, repeat what he says then send peace and blessings upon me because anyone who sends peace and blessings upon me once, Allah will give them the reward of ten (kinds of mercy). Then ask Allah to grant me Al-Wasilah, which is a degree in Paradise that will not be given except to one servant of Allah and I hope that servant will be me. Anyone who asks Allah to grant me Al-Wasilah, they will be given my intercession. (Related by Muslim, Abu Dawud, and Al-Tirmidhy) Also, it was narrated on the authority of `Umar ibn Al-Khattab (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: When the Mu'adhin says, Allahu Akbar (Allah is the Greatest), Allahu Akbar," one should say, "Allahu Akbar, Allahu Akbar." When he says, "Ashhadu an-la ilaha illa Allah (I testify that there is no god but Allah)," one should say, "Ashhadu an-la ilaha illa Allah." When he says, "Ashhadu anna Muhammadan Rasul-ul-Allah (I testify that Muhammad is the Messenger of Allah)," one should say, "Ashhadu anna Muhammadan Rasul-ul-Allah." When he says, "Hay `ala-al-Salah," one should say, "La Hawla wala Quwwata illa billah." When he says, "Hay `ala-al-Falah," one should say, "La Hawla wala Quwwata illa billah." When he says, "Allahu Akbar, Allahu Akbar," one should say, "Allahu Akbar, Allahu Akbar." When he says, "La ilaha illa Allah," one should say, "La ilaha illa Allah." The one who responds (as such) from the heart shall enter Paradise. There is no special Du`a' (supplication) to be said before the Iqamah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
