I think you could do that as an agnostic. Or less involved member of almost any church.
An agnostic, you say?
Here is my take on atheists, agnostics and other non-Muslims in general, using the analogy of a motor car with manual transmission:
Agnostics are in neutral or in other words, they are forever stationary and are not headed anywhere in the ultimate journey of life.
Deists are generally in 1st gear but some of them do pray in their own way and so they would be in 2nd gear. Unfortunately for deists, this is a most inefficient way to drive and this means that they just do not have enough fuel in their tank to last them the whole journey.
People who follow an organized religion like Muslims, Christians, Jews, Hindus, Sikhs etc. would be in anywhere from 3rd gear to overdrive depending on the strength of their belief.
Non-Muslims however, although they may be in overdrive in their zeal towards their faith, are simply headed in the wrong direction and they are very likely to end up going over the edge and into the abyss rather than their intended destination.
Atheists are the most unfortunate group of all for many of them do not even realise that they are in reverse gear.
Therefore, Muslims who faithfully adhere to the teachings of Islam are in the best position of all to enter Paradise because not only are they headed in the right direction, they also are adequately fueled to last the whole journey as they cruise towards their destination in overdrive.
