What is your idea of heaven?

verily I believe in after life, heaven and hell.

now, this is the truth because

the mightiest messengers of almighty God { few listed as Jesus christ ( peace n blessings be upon him ), moses ( peace n blessings be upon him ) Ibrahim ( peace n blessings be upon him ) Joseph ( peace n blessings be upon him ) and the last messenger prophet Mohammed ( peace n blessings be upon him )
and also the four only books from almighty God, named as

1) Tauret ( revealed unto David - peace n blessings be upon him )
2) Zubur also known as old testament ( revealed unto moses - peace n blessings be upon him )
3) Ingil  as new testament or popularly known as Holy Bible  ( revealed unto Christ - peace n blessings be upon him )
and the last book The Glorious holiest Quran for whole mankind revealed unto last messenger prophet Mohammed ( peace n blessings be upon him )

therefore It is written in these greatest, holiest books about hereafter life, heaven and hell and so these messengers of God orally also said. hence, accordingly Jewish brothers n sisters , christians brothers n sisters and muslims brothers n sisters shall believe in After life, heaven and hell verily because whoever believe in these true and mighty messengers and holy books of Almighty God.

If you believe in bible n jesus christ ( peace, blessings be upon him ) then it is logical to believe in hereafter life, heaven.

so is for judaism and so for Islam.
