Sheikh i have a confusion as we know that hajr-e-aswad was not black when it descended from heaven it was pure white but it became black due to sins of mankind so if it was white than who named it hajr-e-aswad because aswad mean black or if this name was given after turning of stone black then what was it’s original name…? Is there any historical information about this in shariah…?
