Six Days. According to me, one Day in this context corresponds to 100 million years. In the Quran, the length of day is not necessarily 24 hours. It varies by context. For example, it says one day on the Day of Judgement is 50,000 years and one Day in Heaven is 1000 years. Six days are the phases or milestones in which the Earth and the Solar system were created following the ignition of the Sun 4.6 billion years ago. As far as religious scholars, there are no priests in Islam. 9-31 They have taken their scholars and monks as lords besides Allah [which is a Sin].
