Deep down within all our cells, and before the necessary proteins for our survival are made, splicing processes take place followed by a reassembly of some of the pieces that will end up as proteins. This splicing process is core to life. It happens at such an amazing rate that it is not fully captured by modern instruments. Furthermore, it is -not- fully understood.
What I mean is that you are physically cut down and reassembled all the time.
One day this process will stop and you will come to pass.
But be certain, that you will be put back together a second time. For you have to account for your deeds before your Maker. It is in the Quran.
Spiritually, you are also carved by “the whips and scorns of times”.
Even then, you should remain composed and forge a way forward with a heart that is full of gratitude to your Maker.

“And We will surely test you with something of fear and hunger and a loss of wealth and lives and fruits, but give good tidings to the patient,
Who, when disaster strikes them, say, “Indeed we belong to Allah, and indeed to Him we will return.”
Those are the ones upon whom are blessings from their Lord and mercy. And it is those who are the [rightly] guided.”
Quran 2:155-157
