It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that on the day of the Conquest of Makkah the Messenger of Allah (peace and blessings be upon him) said: "This is what my Lord promised me." Then he (peace and blessings be upon him) recited: "When the victory of Allah and the conquest come" and then said: "When the people entered the religion of Allah in multitudes, the religion of Allah prevailed over all religions; so the people are upon good, and we are upon good."
Imam al-Tabarani (may Allah have mercy on him) said: "No one except Abd al-Salam bin Harb narrated this hadith from Abu Khalid al-Dalani; Yahya bin Adam is alone in narrating it."
