Musannaf Ibn Abi Shaybah 39698 — Reports on the conquest of Makkah

It is narrated from Ibn Abi Mulaykah that when Makkah was conquered, Sayyiduna Bilal al-Habashi (may Allah be pleased with him) climbed onto the roof of the House of Allah and called the adhan. Safwan bin Umayyah said to al-Harith bin Hisham: "Do you not see this slave?" Al-Harith said: "If Allah Almighty disliked this, Allah Almighty would put someone else in his place."
