It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Quraysh said to the Noble Prophet (peace and blessings be upon him): Pray to your Lord that He may turn the mountain of Safa into gold for us, and we will believe in you. The Prophet (peace and blessings be upon him) said: Will you really do so? They said: Yes. So when the Prophet (peace and blessings be upon him) prayed, Jibreel (peace be upon him) came to him and said: Indeed, your Lord sends you greetings of peace and says: If you wish, the mountain of Safa will be turned into gold for them, but whoever disbelieves after this sign, I will punish him with such a punishment as I have not given to anyone in the worlds. And if you wish, I will keep the doors of repentance and mercy open for them. The Prophet (peace and blessings be upon him) said: The door of repentance and mercy is better.
