He communicated that some people will remain in Hell for ever

one very common superstition in ignorant societies is that people will remain in hell for a given length of time and then leave it. however, allah has made it known that some people will remain in hell for ever. in accordance with allah's command, the prophet (saas) told those who believed that one will only remain in hell for a given period that some people will stay there permanently: they say, "the fire will only touch us for a number of days." say, "have you made a contract with allah-then allah will not break his contract-or are you rather saying about allah what you do not know?" no indeed! those who accumulate bad actions and are surrounded by their mistakes, such people are the companions of the fire, remaining in it timelessly, for ever; whereas those who believe and do right actions, such people are the companions of the garden, remaining in it timelessly, for ever. (surat al-baqara: 80-82)
