Is it true that the complexions of people in Jannat will be only white?

Answer

Whether the complexions of people in Jannat will be only white or also of other colours is known to only Allah Ta'ala. Whatever Allah Ta'ala wills, creates and selects is best. We are His creation. We do not comprehend His Wisdom. He does as He pleases. He is the Creator, The Wise and The Most Powerful. We puny creatures with our created brains with their finite and limited understanding cannot embrace in comprehension Allah's Power and Wisdom. It is not our obligation to fabricate interpretations for whatever He wills and for the complexions He will be bestowing to people in Jannat.
