The du‘ā’ to be said after the adhān
Context
WE RELATE FROM Anas 
that the Messenger of Allah 
said: “A supplication between the adhān and the iqāmah is never rejected.” [1].Abū Dāwūd, at-Tirmidhī, an-Nasā’ī and Ibn as-Sunnī narrated it, as well as others. At-Tirmidhī described this hadith as ḥasan ṣaḥīḥ. At-Tirmidhī added in his version in the Book of Prayers from his Jāmi‘: They asked: “What should we say, Messenger of Allah?” He said: “Ask Allah for well-being in this world and the Hereafter.”
