Praise be to Allaah.
Allaah created Adam (peace be upon him) on a Friday, the sixth day from the beginning of creation. Some texts mention what was created on the previous five days, in brief and general terms, but as to the details of what was created, Allaah knows best about that. Questions like this, on which no belief or deeds are to be based, are just meaningless distractions that are of no benefit. Faith does not increase or decrease according to whether one believes in dinosaurs or not. It was reported that the Prophet (peace and blessings of Allaah be upon him) forbade us to occupy ourselves with things that cause confusion and are not clear. We also know that people differ in their views as to whether these dinosaurs existed or they are just figments of the imagination. And Allaah knows best.
