In the name of God, Most Beneficent, Most Merciful.
1) Your question: Many people believe and say that drawing cartoon character or non living thing, or person without soul is allowed. I want to know if that is true?
It is true, in fact, this was told by angel Gabriel to prophet Muhammad. I’ll provide you an evidence. So here it is:
Sahih Al-Bukhari Hadith 7.841 Narrated by Abu Talha
The Messenger of God (saws) said:
”Angels (of Mercy) do not enter a house where there are pictures and dogs."
Sahih Al-Bukhari Hadith 4.450 Narrated by Abu Salim
Once Gabriel promised the Prophet (saws) that he would visit him, but Gabriel did not come, and later on he said, "We, angels, do not enter a house which contains a picture, or a dog."
2) Your question: Can I draw popeye?
I’m sorry, but it is not allowed. I’ll give you a Hadith for this.
Sahih Al-Bukhari Hadith 3.428 Narrated by Said bin Abu Al Hasan
While I was with Ibn 'Abbas a man came and said, "O father of 'Abbas! My sustenance is from my manual profession and I make these pictures." Ibn 'Abbas said, "I will tell you only what I heard from God’s Apostle. I heard him saying, 'Whoever makes a picture will be punished by God till he puts life in it, and he will never be able to put life in it.' " Hearing this, that man heaved a sigh and his face turned pale. Ibn 'Abbas said to him, "What a pity! If you insist on making pictures, I advise you to make pictures of trees and any other unanimated objects."
From this Hadith, we learn that it is permissible to make any image unanimated things. And if you do make any image that has soul, then you have committed one of the major sins.
The main reason for the prohibition of image making is because, it is an imitation, it imitates God.
And Bukhari, Tirmidhi, and Imam Nasa’i relate the prophetic hadith form Ibn Abbas, “Whoever makes a picture, God shall torture him with it on the Day of Judgment until he can breathe life into it, and he will never be able to.”
The reason for the unlawfulness of pictorial representation is that it imitates the creative act of God Most High, as is indicated by the hadith related by Imam Bukhari and Imam Muslim that A’isha (God be well pleased with her) said, “The Prophet (God bless him and give him peace) returned from a trip, and I had draped a cloth with picture on it over a small closet. When he saw it, he ripped it down, his face colored, and he said, “A’isha, the people most severely tortured by God on the Day of Judgment will be those who try to imitate what God has created.”
I’ll provide you another Hadith that it speaks about image making. So here it is:
God’s Messenger said: “Those who make these images will be punished on the Day of Resurrection and it will be said to them, ‘Make alive what you have created.’” [Bukhaari and Muslim]
Narrated ’Aaishah radiyallaahu’anhaa: God’s Messenger sallallaahu’alaihiwasallam returned from a journey when I had placed a curtain of mine having images over the door of a chamber of mine. When God’s Messenger sallallaahu’alaihiwasallam saw it he tore it apart and said: “The people who will receive the severest punishment on the Day of Resurrection will be those who try to make the like of God’s creation.” [Bukhaari]
If you really have to make an animated thing, then you must have the following reasons:
-Photos of criminals for the purpose of identification and then arrest when they commit a crime or attempt to flee.
If you do have respected this list I have you, then there’s no sin upon you.
And if you really want to make an animated this, then God the Glorious and Exalted said,
”Who is more a wrongdoer than one who tries to create creation like My creation. Let him create a small ant or a grain of wheat.” [Muslim]
Here it means you can make any unanimated things, things that do not posses a soul such as: a car, rock, planet, stars, plains etc.. this is ok to make.
3) Your question: Is drawing something through digital is also prohibited?
According to my knowledge, digital art is not forbidden, because it does not come under the prohibition of image making. You can draw any picture you want with condition not to print it and with condition not to make any woman naked.
I hope that I gave you a good answer.
