The enduring good deeds.
The reward for those who call the adhan and the reward for the front row.
On the authority of al-Bara' Ibn 'Azib, may Allah be pleased with them both.
That the Prophet of Allah, peace and blessings of Allah be upon him, said:
"Indeed, Allah and His angels send blessings upon the front row."
"And the one who calls the adhan is forgiven to the extent of his voice."
"Everything that hears him, whether moist or dry, confirms his testimony."
"And he shall have a reward equal to those who pray with him."
