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.”

that a man said: “O Messenger of Allah, the callers of the adhān are superior to us.” The Messenger of Allah said: “Say what they say; and when you have finished, ask and you will be given.” [2].Abū Dāwūd narrated it and did not consider it weak.

that the Messenger of Allah said: “Two supplications are never rejected”—or “Are rarely rejected”: “one at the time of the call to prayer, and one at the time of strife when some do battle with others.” [3].In some reliable texts, the word yulḥimu with the letter ḥā’ appears, whereas other narrations have the letter jīm. Both are clear in their meaning.
