Staaaaahp it. Y'all be sounding like that hippy dippy new Pope, "just do good and anyone can end up in Heaven, whether you believe in Jesus or not!".
"And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers." Quran 3:85
There's your God speaking, saying you will catch an L if you do not follow his religion.
Any contrary interpretation is a mockery of your God's messenger delivery system, what need to learn Islam's specific practices then? If the test in life is to just be good, the test is already in motion without God meddling further and sending supposedly 120,000 messengers around the globe at various times all prior to the 7th Century.
Let me just say humans who claimed Prophethood to deliver a divine message is not unique, there were many before Muhammad and many after him. He just claimed to be the last and delivered the Quran as his "proof", a rambling incoherent scripture containing scientific inaccuracies. The fact that anyone considers it the word and work of a supernatural diety is beyond me.
