Question

Why people disobey Allah?

Answer

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
If you are referring to the reason why people sin, then there are many reasons for this, among which are the following:
1- One’s ignorance of Allah and of His Names and Attributes, because if one is more knowledgeable of Allah, he would be more fearful of Him; it is for this reason that the Prophet said: “I am the most pious amongst you and the most knowledgeable of Allah amongst you.” [Al-Bukhari] This Hadeeth was narrated by ‘Aa’ishah, may Allah be pleased with her.
2- Being deceived in respect of the forbearance of Allah and Him giving respite to His Slaves and Him not hastening the punishment for them; Allah Says (what means): {And if Allah were to impose blame on the people for what they have earned, He would not leave upon it [i.e. the earth] any creature. But He defers them for a specified term. And when their time comes, and then indeed Allah has ever been, of His servants, Seeing.}[Quran 35:45]
3- Weakness of faith and the heedlessness that afflicts the hearts; Allah Says (what means): {No! Rather, the stain has covered their hearts of that which they were earning.}[Quran 83:14] Allah also Says (what means): {I will turn away from My signs those who are arrogant upon the earth without right; and if they should see every sign, they will not believe in it. And if they see the way of consciousness, they will not adopt it as a way; but if they see the way of error, they will adopt it as a way. That is because they have denied Our signs and they were heedless of them.}[Quran 7:146]
4- Having long hope (in life), following desires, having a hardened heart, and being lured by this world and by its adornments. Allah Says (what means): {Has the time not come for those who have believed that their hearts should become humbly submissive at the remembrance of Allah and what has come down of the truth? And let them not be like those who were given the Scripture before, and a long period passed over them, so their hearts hardened; and many of them are defiantly disobedient.}[Quran 57:16] Allah also Says (what means): {…and do not follow [your own] desire, as it will lead you astray from the way of Allah.}[Quran 38:26] Allah further Says (what means): {So let not the worldly life delude you.}[Quran 31:33]
5- The devil: He is the master of temptation and the pivot of evil, as Allah Says on his tongue (what means): {[Satan] said, “Because You have put me in error, I will surely sit in wait for them [i.e. mankind] on Your straight path. Then I will come to them from before them and from behind them and on their right and on their left, and You will not find most of them grateful [to You].”}[Quran 7:16-17]
