As Salaam Alaikum Sister,
From the knowledge that I know, no man has gone to the heavens to talk about it what they've seen aside from that of which has been told to us by Allah (swt). The Day of judgement has yet to come and thus no man or female has been judged to be sent to Jannah or Jahanam. So no it is not real. Also one reason Islam should be followed instead of Christianity or any other religion is that the words that has been written in the Qu'ran, the words passed down to mankind from Allah, has never been changed once for 1400+ years. When you take the different versions of the bible and compare then to each other, you'll notice a trend of changes in a period of time, so basically every some years, the bible would be changed, something would be added to contradict something that was already written that didn't satisfy people of that era. Prophet Isa, also known as Jesus, states in the Bible, Luke 4:8, Jesus answered him, "It is written, 'YOU SHALL WORSHIP THE LORD YOUR GOD AND SERVE HIM ONLY.'" Jesus himself states that you are to worship one god and one god only, and that was his [FONT=Trebuchet, Arial, Helvetica, sans-serif]reference[/FONT][FONT=Trebuchet, Arial, Helvetica, sans-serif] to Allah (swt). Islam also doesn't say that Jesus was a lie, no in fact he was one of our Prophets as you may know, and he still serves a purpose in the distant future, as the Messiah of this world. In the history of Islam, the fetus was described to mankind through the Quran and how a fetus was created, starting with the male sexual cell and its process before it was even scientifically proven. In Islam, there are chains to names, Prophet Muhammad's peace be upon him, name had a last name and a chain to follow and so did every other Muslim after him and Prophet before him. However, who was Luke? Which family did he belong too? Who was John? What was his family roots? [/FONT]
