I want to know do Jewish people believe in god and in heaven and hell.

Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

Jews believe in Allah but describe Him as miserly as Allah Says (interpretation of meaning): {The Jews say: "Allâh's Hand is tied up (i.e. He does not give and spend of His Bounty)." Be their hands tied up and be they accursed for what they uttered. Nay, both His Hands are widely outstretched. He spends (of His Bounty) as He wills …} [5: 64].
They also say that Allah is poor. Allah Says (interpretation of meaning): {Indeed, Allâh has heard the statement of those (Jews) who say: "Truly, Allâh is poor and we are rich!" …} [3: 181].
They also say that Allah is weak and gets tired claiming that He created Heavens and Earth in six days then got tired and had a rest on the seventh day. Allah Says (interpretation of meaning): {And indeed We created the heavens and the earth and all between them in six Days and nothing of fatigue touched Us.} [50: 38].
They fabricated many more lies and Allah denied them all.
Jews believe in Paradise but claim it is only for them Allah Says (interpretation of meaning): {And they say, "None shall enter Paradise unless he be a Jew or a Christian." …} [2: 111].
They also believe in Hell and say that it will affect them for only some limited days. Allah Says (interpretation of meaning): {… they say: "The Fire shall not touch us but for a number of days."…} [3: 24].
They also believe in the torment of the grave as reported in a sound Hadith in al-Bukhari and Muslim . But they are Kafir (disbelievers) because they do not believe in Prophet Muhammad (Sallallahu Alaihi wa Sallam) and his Sharia and they make lawful to them what is unlawful and they changed the Torah.
Allah knows best.
