How to Answer the Adhan Correctly According to Sunnah, Complete with Its Rulings and Duas
The majority of scholars hold that answering the adhan is sunnah muakkadah, based on the hadith of Prophet Muhammad PBUH: "When you hear the call to prayer, say what the muezzin says" (Sahih Muslim). Muslims are encouraged to repeat each phrase uttered by the muezzin, except when hearing "hayya alash shalah" and "hayya alal falah," which are answered with "laa haula wa laa quwwata illa billah."
Here are the adhan phrases and their responses: "Allahu Akbar" is answered the same, "Asyhadu alla ilaha illallah" the same, "Asyhadu anna Muhammadan rasulullah" the same, "Hayya alash shalah" and "Hayya alal falah" answered "Laa haula wa laa quwwata illa billah," and "Allahu Akbar" and "La ilaha illallah" the same. For the Fajr adhan, the addition "Ash-shalaatu khairum minan naum" is answered with the same phrase.
After the adhan, it's recommended to recite the dua: "Allahumma rabba haadzihid da'watit taammah..." (mentioned in full) which means seeking wasilah and virtue for Prophet Muhammad PBUH. The etiquettes of listening to the adhan include stopping what you're doing, answering the adhan according to the guidance, sending blessings on the Prophet, and reciting the dua after the adhan.
