It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Whoever gives the adhan for twelve years, Paradise becomes obligatory for him, and he receives sixty good deeds for every adhan and thirty good deeds for every iqamah." Imam al-Hakim says: This is also supported by the narration of Ibn Lahi'ah, whom Imam Muslim cited as a supporting narrator.
