hazrat khizar a.s ney hazrat musa a.s key sath safar main jo kaam kiey aur ( bachay ko maarna aur dewaar ghirani ) aur hazrat musa a.s key poochnay per jab un ki reasons bataieen, to kia yeh future ka ilm nahi tha ?
That is a good point. However if you read in detail, that ALLAH gave Hazrat Khizar FUTURE info about THREE specific incidences to guide Hazarat Musa as.
But Hazrat Khizar did not layout the future info on all the aulad of Hazrat Musa.
Hazrat Khizar did not predict future life of Hazrat Musa either.
So you see the difference?
A Nabi may have tiny bits of info for a specific event in HIS life. But Nabis do not layout nor predict complete life spans of nations or individuals.
I hope you understand the difference.
