Hi new seed
Never ever said in the Quran that the bible was not corrupted in the Muhammed saw's time.. it was corrupted already thats why Allah sent another prophet to remind us..
and yes Allah says believe in what I send the prophets and books.. otherwise.. we could say Muhammed saw is the only prophets of Allah and the first and last.. no we believe in all prophets and their books.. but we believe also todays books is been chnaged so we cant use them anymore but once they were here , sent by same Allah and they had their books and it was wirtten what Islam teaches..before corrupted.
So we believe the ones in original way.. not todays corrupted way..
