Jami` at-Tirmidhi Book 48, Hadith 225
“The supplication is not rejected between the Adhan and the Iqamah.” They said: “So what should we say, O Messenger of Allah (ﷺ)?” He said: “Ask Allah for Al-`Afiyah in the world and in the Hereafter.”
“May my father and my mother be ransomed for you, O Messenger of Allah (ﷺ)! Which speech is most beloved to Allah ?” So he said: “That which Allah selected for His angels (to say): ‘Glory to my Lord, and with His praise. Glory to my Lord, and with His praise (Subḥāna rabbī wa biḥamdihi, subḥāna rabbī wa biḥamdihi).’”
“The supplication is not rejected between the Adhan and the Iqamah.”
