Musannaf Ibn Abi Shaybah 2386 — What a man says when he hears

Al-Hasan said: When you hear the muezzin, say the same words that the muezzin says, except that when he says 'Hayya 'ala al-salah' (Come to prayer), you should say: 'La hawla wa la quwwata illa billah' (There is no might nor power except with Allah). When he says 'Qad qamat al-salah' (The prayer has been established), say these words: O Allah, Lord of this perfect call and of the prayer about to be established, grant Muhammad (peace and blessings be upon him) on the Day of Resurrection what he has asked of You. Whoever makes this supplication at the time of the iqamah, Allah will admit him on the Day of Resurrection into the intercession of the Prophet (peace and blessings be upon him).
