What about divorce in Muslim religion?

Answer 1

Allah subhanahu wata'al mentioned marriage many times in the Quran in different meanings and subjects in order to teach Muslims. Such as:

"And marry the unmarried among you and the righteous among your male slaves and female slaves. If they should be poor, Allah will enrich them from His bounty, and Allah is all-Encompassing and Knowing. (32) " Surat Al-Noor"

and said:

"And Allah has made for you from yourselves mates and has made for you from your mates sons and grandchildren and has provided for you from the good things. Then in falsehood do they believe and in the favor of Allah they disbelieve? (72) "Surat Al-Nahl"

and said:

"And do not marry polytheistic women until they believe. And a believing slave woman is better than a polytheist, even though she might please you. And do not marry polytheistic men [to your women] until they believe. And a believing slave is better than a polytheist, even though he might please you. Those invite [you] to the Fire, but Allah invites to Paradise and to forgiveness, by His permission. And He makes clear His verses to the people that perhaps they may remember. (221)"

and many many verses in the Quran dealth with marriage, ansestors, decindents ... etc.

The Quran and the Sunnah dealth with all aspects of life of a Muslim even before he is born "by choosing a good mother", to his death and resurrection on the doomsday.
