dontconvert2islam begins seeing the intricacies; Allah endows mankind with spirituality?

In answer to the video "Worst Creatures in Islam"

God has created in man the innate ability to come to such conclusion through reason and observation. That hardwired spirituality also leads one to understand the great evils and make the essential correct spiritual choices. Each person is thus at least responsible for his response to that basic guidance even if it isnt directly spelled out to him. 

That innate guidance is the essential thing seperating us from animals. Contrary to us, morally accountable creatures, animals are not blameable for certain acts like unjust killings (infanticide) or detestable practices (cannibalism) that humans, regardless of their religion or belief (or lack of belief) in God outright reject. This innate guidance must be nurtured or it degrades and dies, leaving its host without any proper moral and spiritual compass. The neglect and degradation of this God-given tool is something the individual will have to answer to before God 7:172-3,75:2,91:7-10.  

So for anyone, Muslim or else, to be included among the succesful in the Hereafter, indiscriminately, regardless of faith and appellations, described in 64:9 as "whoever believes in Allah", then their belief in God will have to be in accordance with their innate guidance and common sense, and the nature of their deeds may not conflict with their innate capacity to understand good and evil. This means that in any case, a deed is only good because it is in accordance with God's revealed principles. However, some are at a disadvantage even when it comes to hearkening that basic, ingrained guidance. They are those brought up in a heavily corrupt environement. 

God will definately take this factor into account as seen with the Queen of Sheba's case whose disbelief was blamed on her corrupt environement and sinful conditionning 27:43. However that conditionning can still be reversed once guidance is properly conveyed to them or when they leave their atmosphere, as equally seen with the Queen who reformed herself after coming in contact with the prophet Solomon who demonstrated to her what constitutes spiritual uprightness. Some lack the mental capacity to discern the truth and arent therefore accountable for failing in this regard

36:62,35:37"Did We not preserve you alive long enough, so that he who would be mindful in it should mind?"

If a person has died before attaining such an age, ie "long enough to be mindful" he will not be called to any account according to this verse. However, the one who has attained this age will certainly be held answerable for his actions and from that point on, for any positive or negative answer to the opportunities of spiritual betterment. Other people despite posessing their full intellectual capacities havent been properly explained the teachings of Islam, and thus logically cannot be held accountable for rejecting something that was misrepresented, willfully or not, to them

3:163,6:132"And all have degrees according to what they do; and your Lord is not heedless of what they do"  

46:19"And for all are degrees according to what they did, and that He may pay them back fully their deeds and they shall not be wronged".

These intricacies are impossible to be fully encompassed by the human mind so that someone, in this world, may declare another to be destined for Heaven or Hell. Not even a divinely appointed prophet may do such a thing

46:9"say: I am not the first of the messengers, and I do not know what will be done with me or with you: I do not follow anything but that which is revealed to me, and I am nothing but a plain warner"  

39:62"He alone has the power to determine the fate of all things"  

31:34"and no one knows what he shall earn on the morrow; and no one knows in what land he shall die; surely Allah is Knowing, Aware".

When on the Day of Judgement, the prophets and messengers are called to testify as to the answer of those reached by their message, they will humbly reply 1

6:84,89,7:6,5:109"We have no knowledge, surely Thou art the great Knower of the unseen things".

These noble witnesses only knew of that outward response which was made to them, but only Allah knows how the message was received by each individual, how far the rejecters were or how far the followers truly believed and remained true to it during and after the death of the messengers. In the words of Jesus on the day of judgement

5:117"I did not say to them aught save what Thou didst enjoin me with: That serve Allah, my Lord and your Lord, and I was a witness of them so long as I was among them, but when Thou didst cause me to die, Thou wert the watcher over them, and Thou art witness of all things".
