I have few Question About calculating time period according to Islam
Is there anyway to calculate how long this Universe has existed for Quran or Hadith?
How long did Hazrat Adam(a.s) lived?
For how long human has been living in this world?
I have been confused about the calculation of time these question have been in my mind for long time now. I want to if there is a answer in Islam about this. I know will be hard to tell but is there a time explanation in Islam. I know there were no units of second and hour so how Allah calculate time?
