A: Why would a manufacture not service your car if they are true manufactures standing guarantee for the quality of their product upon your refusal to do its oil changes as specified and thus allow for a possibly blow up engine to be placed in a junk yard (type of hell for cars)?
Likewise, Allah (SWT) is Just, this requires that He sets down rules via Quran and hadith. Those that follow the rules attain heaven, those Muslims that reject the rules would likewise attain its consequences.
Allah certainly Knows Best.
