It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Quraysh demanded from the Prophet (peace and blessings be upon him) to supplicate to his Lord to turn the mountain of Safa into gold for them, and they would believe in him. The Prophet (peace and blessings be upon him) said: "Will you really believe?" They said: "Yes!" The Prophet (peace and blessings be upon him) supplicated. Jibreel (peace be upon him) appeared and said: "Your Lord sends you greetings of peace and says: 'If you wish, I will turn the mountain of Safa into gold for them, but after that, if any of them disbelieves, I will punish him with a punishment that I have not given to anyone among all the people of the world. And if you wish, I will open for them the door of repentance and mercy.'" The Prophet (peace and blessings be upon him) said: "Rather, open for them the door of repentance and mercy."
