The Muslim wayfarer to Allah the home of the hereafter, is unable to complete his journey to his Lord in the absence of three bits of luggage.

There can be no pleasing of Allah, no safety in the grave, no help in the hereafter,  nor success when we arrive at the gates of Paradise Without these three pieces of luggage:
The first is to unify Allah Almighty in worship.
And the second piece of luggage is ..conformity to the Prophetic way.
And the third of them is .., the purification of the soul.
There is no success without them. It was the provision of every prophet and righteous man and woman till the end of times.
