is all sort of doodling haram?

the ruling is found in the statement of Allah’s Messenger (sal-allahu alayhi wa sallam):
It is not permissible to draw and make images of animate beings, whether they are engraved, on paper, on cloth or anything else, because of the report narrated by al-Bukhaari (2105) and Muslim (2107) from ‘Aa’ishah the Mother of the Believers (may Allaah be pleased with her), that she bought a cushion on which there were images. When the Messenger of Allaah (peace and blessings of Allaah be upon him) saw it, he stood at the door and did not enter. She said: I recognized displeasure in his face. I said: O Messenger of Allaah, I repent to Allaah and His Messenger, what have I done wrong? The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “What is this pillow?” She said: I bought it for you to sit on and recline on. The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “The makers of these images will be punished and it will be said to them, ‘Bring to life that which you have created.’” Then he said: “The house in which there are images is not entered by the angels.”

And Muslim (2110) narrated that Sa’eed ibn Abi’l-Hasan said: A man came to Ibn ‘Abbaas and said: I am a man who makes these images; advise me about that. He said to him: Come close to me. So he came closer to him. He said: Come closer to me. So he came closer to him, until he put his hand on his head and said: I will tell you what I heard from the Messenger of Allaah (peace and blessings of Allaah be upon him). I heard the Messenger of Allaah (peace and blessings of Allaah be upon him) say: “Every image maker will be in Hell, and for every image that he made, a soul will be created which will punish him in Hell.” He said: If you must do that, then make (images of) trees and inanimate things.

Al-Nawawi (may Allaah have mercy on him) said in Sharh Saheeh Muslim: Our companions and other scholars said: Making images of animals is emphatically haraam and is a major sin, because this stern warning which is mentioned in the ahaadeeth is issued concerning it. That applies whether he makes it to be used in ways that are not respectful or otherwise. Making it is haraam in all cases, because it is competing with the creation of Allaah. That applies whether the image is in a garment or a carpet or a dirham or a dinar or a penny or a vessel or a wall or anything else. As for making images of trees, camel saddles and other things in which there are no images of animals, that is not haraam.

Islam Question and Answer - Is it permissible for children to draw pictures of animate beings?
@hareem

Please let sincere people learn about their deen.

I have advised you before that do not speak without knowledge or issue your personal fatawas. You are a layperson like rest of us but you go around mocking the understanding of the scholars and saying “fullan is haraam or fullan is halal”. Do you have any evidence for what you say? What I said before is what I learned from trustworthy traditional scholars, who DEFINITELY know what they are talking about and do no speak from their desires.

What you have stated above is utter rubbish (calling such Muslims extremists). This whole idea of extremists/fundamentalists/strict Muslims is a oxymoron. By definition, a Muslim is one who submits to the Will of Allah, meaning the Commands and rulings of Allah. To say one can be a Muslim but let not be so extremists by submitting oneself to every Command of Allah, is an oxymoron and contradiction. What do you want us to do, give up certain rulings of religion so that you are pleased and say “oh look we Muslims are not strict or extreme” or “masa’Allah look fullan is not so strict”. I hardly have any words to describe this blunder and rubbish idea and specially when it comes from Muslims.
