Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (sallallaahu ’alayhi wa sallam) said,

“If people came to know the blessing of calling Adhan and the standing in the first row, they could do nothing but would draw lots to secure these privileges.”

[Al-Bukhari and Muslim]
