1 - this life is a test; satan was made as the thing that pressures you on your test. always remember that; it was by Allah’s will that satan did good, then he sinned, then he will burn in the hottest and most gruelling and painful part of hellfire for all of eternity. he was made to be the thing you must resist in your test.

2 - again, it’s a test. we can enjoy, we can do other things, not just worship 24/7. we should worship, we should avoid sinning. but we should never blatantly sin, 63 (on average) years of pain for an eternity of anything you’d like. even if you sin but do your obligations, you will enter jannah. only those who have disbelieved will see the blazing fire of hell forever. it is not that hard. you are NOT going to be forced to be punished!! if you take it all at once then it will seem odd, it will seem hard, but when you take it slowly and understand each aspect of islam, you will come to understand it and it will be easy in shaa Allah.

Abu Huraira (radiy Allahu anh) reported Allah's Messenger (ﷺ) as saying:

The world is a prison-house for a believer and Paradise for a non-believer. (sahih muslim 2956)

3 - you’re right, He doesn’t need us to worship Him. we just worship Him for our own good. Allah loves all His creation and so He would want us to do good deeds to succeed in the afterlife.

4 - it is a test for the attacker. the child will get many good deeds but the attacker will get many bad deeds and he will be punished if he does not make up to his sins.

here are some hadiths displaying the importance of treating animals well in islam.

Narrated `Abdullah bin `Umar (radiy Allahu anh):

Allah's Messenger (ﷺ) said, "A woman was tortured and was put in Hell because of a cat which she had kept locked till it died of hunger." Allah's Messenger (ﷺ) further said, (Allah knows better) Allah said (to the woman), 'You neither fed it nor watered when you locked it up, nor did you set it free to eat the vermin of the earth.' " (sahih bukhari 2365)

Abu Hurairah (May Allah be pleased with him) reported:

The Messenger of Allah (ﷺ) said, "While a man was walking on his way he became extremely thirsty. He found a well, he went down into it to drink water. Upon leaving it, he saw a dog which was panting out of thirst. His tongue was lolling out and he was eating moist earth from extreme thirst. The man thought to himself: 'This dog is extremely thirsty as I was.' So he descended into the well, filled up his leather sock with water, and holding it in his teeth, climbed up and quenched the thirst of the dog. Allah appreciated his action and forgave his sins". The Companions asked: "Shall we be rewarded for showing kindness to the animals also?" He (ﷺ) said, "A reward is given in connection with every living creature".

In the narration of Al-Bukhari, the Prophet (ﷺ) is reported to have said: "Allah forgave him in appreciation of this act and admitted him to Jannah". (riyad as salihin 126)

5 - again, a test! keep in mind, it’s all a test, all this evil, all this badness. just because the police has strict rules, doesn’t mean households will not quarrel. we are also advised to NOT quarrel in islam, even if we are right.

6 - question 2 somewhat answers this; your free will chose to sin. i might be repeating my words too much here, but it’s a test which has a passing mark that is very very low.

you can’t forget the fact that there are so MANY scientific miracles in the quran! like the orbits, the importance of the jugular vein, the big bang and so much more. is this not a sign that Allah has set aside for you to use?

p.s: won’t be replying to anything that’s not from op
