The opening as it read in 2005

Bilal ibn Rabah (died c. 640 ) was an Ethiopian born in Mecca , whom Muhammad chose as his muezzin , and was the first black convert to Islam .1 He was known for his beautiful voice with which he called people to their prayers. mother was Hamamah He was a slave owned by Umayya .2 When he heard Muhammad preach, he decided to convert to Islam. When Umayya learned of his slave's conversion, he tortured Bilal in order to force his apostacy. Umayya commanded that Bilal be laid in the scorching sand in the desert, during the hottest hours of the day, with heavy rocks placed on his chest to prevent him from moving. Abu Bakr , upon witnessing this torture, bought Bilal from Umayya, and permitted Bilal to practice Islam freely. Muhammad later freed him completely and appointed him as muezzin. As soon as Abu Bakr asumed power, he stoped singing the adhan. Bilal also carried Muhammad 's spear, which was used from 624 onward to point the direction of prayer. He was present at Badr and all of the major events. He died in Damascus in 17 or 18 AH, but some say 20 AH, or even 21 AH when he was just over sixty years old. Some said he died in Madinah, but that is wrong. That is how it is in al-Isabah and other works such as the Tahdhib of an-Nawawi.3
