The Voice of Bilal Ibn Abi Rabbah

The first voice to ever call out or eat in Mecca was the voice of Bilal, Ibn Abi Rabbah. That same voice was then hoisted on top of the Kaaba at the pinnacle of honor. He was told to give the first-a-than-ever in the sacred precincts of the haram. The Prophet said that if people knew how much reward would be in the giving the a-than and in standing in the first-row, they would not just give it up.
