Not sure if you have studied Islam and Quran and trying to understand Abrahamic religion mostly through Christianity.

In my observation Christians struggle with the concept of suffering and pain , because if Jesus died on the cross and took away sins than what is the point of doing actions and why there is suffering and chaos ( Muslims might find other problem with religion and especially get attracted to wester ideas, especially west being a dominant power as its able to exploit materialism well)

Abrahmic faith, even every prophets preached monotheism which goes like below , Christians mostly changed what Jesus preached and eventually it caused harm to religion and eventually people struggled to grapple with religion

We have weaknesses and life is a test to go against those weaknesses, by holding on to the One and asking for help.

Satan (and its party) are our enemies, it wants to divide humans and make them busy and keep them busy fighting each other.

Life is a test; all acts are recorded, and we are judged based on it.

Truth and Beauty are human endeavors, if one follows them and tries to implement them will find God.

We are humans, not animals and we have a consciousness that guides us, but we need to keep the above endeavor and will help keep a sound heart and God will guide us.

Humans are vicegerent (of the One) to this world, and they have been given the ability and luxury to explore this world and universe and make it useful for themselves.

Any group of humans (family, tribe, society) can only survive if it is based on justice; otherwise, corruption will enter it and eventually, it will be destroyed.

There are sets of dos and don’ts, don’t is pretty much common in all Abrahamic religions (alcohol, interest, fornication, eating kosher), other than it demands certain obligations (do’s) which vary between them; but the general ruling and guidance, appeal to human morality by promoting to speak the truth, being honest, clean, fulfill obligations, don’t break blood relationship, love your neighbor,…

Try to stop bad from happening, try to do it with your hand, if not then with your tongue, and if not at least consider it bad in your heart.

There is more to it, but the above covers mostly the basics, and it's quite simple.
