There is more, there is always more than we as humans could ever know.
To obtain both the best in this world and the next is entirely dependant on perspective.
Perhaps, you could already have the best in this world but have not yet come to notice.
See how people always want to enjoin evil, the majority of the folk even rush to it. Places in the world, which are known for their Qur’anic roots, have been surrounded by evil, merely for the enjoyment of tourists, the pleasure of people.
There is so much good, and what reward can you reward someone good except that it is also good?
We are unappreciative as humans, also ungrateful. Perhaps this may be wrong, depending on how you saw the information presented, of course, you should work in the world but concentrate on what is with Him.
Taking the best from every information presented and not to follow the footsteps from the shaitan, keeping oneself on track by reaffirming belief that there is only one God.
The next branches of faith are to establish the prayer, with need to say whilst in a state of purity, establishing means to make something scheduled and permanent by intention.
Giving to charity as much as one can despite sometimes the fear of poverty, instead of the bare minimum. Of course, there is more to it than that, for perfectly valid reason, which someone of common sense otherwise known as understanding would acknowledge.
Indeed, with the obligatory, if one were to upkeep all the minimum requirements of Islam with the right intention, then they would be admitted into their heaven.
In this day and age, how much does one miss or how much does one deny their Lord, that we should be worried that it is not ever sufficient?
Not one person will enter Heaven based on their actions alone.
Indeed this is why, to humans, our Lord is the Most-Merciful.
