Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated from the Messenger of Allah (peace and blessings be upon him) that he (peace and blessings be upon him) said: "Whoever gives the call to prayer (adhan) for seven years seeking reward for the sake of Allah, freedom from Hell will be written for him."

It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that he said: To have the ability to call the adhan with the intention of reward for the sake of Allah’s pleasure is more beloved to me than jihad, Hajj, and ‘Umrah.
