You start having this cleavage occur right here.

So immediately after fertilization, this zygote starts experiencing cleavage.

And this has become such a cultural norm that we actually school our children for them to be capable to do this cleavage.

This shall be because Allah hath verily sent down the Book with truth and verily those who differ respecting the Book. are surely in cleavage wide.

By the end of telophase in mitosis, you also have this process of cytokinesis, where this cleavage furrow forms and deepens, deepens, deepens until the cytoplasm is actually split into two separate cells.

So if they believe in the like of that which ye believe in, surely they are guided but if they turn away, then they are but in Cleavage. So Allah will suffice thee against them and He is the Hearer, the Knower.

Then on the Judgment Day He will humiliate them and say where are My associates regarding whom ye have been causing cleavage? Those who have been vouchsafed knowledge will say verily the humiliation to day and ill hap are upon the infidels

And, O my people! let not the cleavage with me incite you so that there befall you the like of that which befell the people of Nuh and the people of Hud and the people of Saleh and the people of Lut are not from you far away.

Now, at the same time telophase is happening, you also normally have this cytokinesis, where this cleavage furrow forms, where essentially during telophase, these things are getting pushed further and further apart by those microtubules so that they're already at the ends of the cell, of the cytoplasm of the cell, and you can almost view them as pushing on the sides to elongate the cell.
