No, a foal from a grey horse does not necessarily have to become grey. The grey color in horses is a result of a dominant gene that causes the horse's coat to lighten over time. However, the foal's color is determined by the combination of genes from both its parents, so if the other parent carries a different color gene, the foal may inherit that color instead. Additionally, some grey horses may produce non-grey offspring if they carry other color genes that are passed on to the foal. **

Instead, it focuses on the use of color, shape, form, and gestural marks to create a composition that is non-representational and often non-objective. Abstract paintings can evoke emotions, ideas, and sensations through the use of non-representational elements, allowing for a more subjective and personal interpretation by the viewer. This style of painting emerged in the early 20th century and has since become a significant and influential movement in the art world. **

Some scholars consider abstract drawings to be permissible as long as they do not depict anything that is prohibited in Islam, such as nudity or idolatry.

It is important for individuals to seek guidance from knowledgeable scholars and to consider the intention and context behind the creation and use of abstract drawings. **

No, a dun horse cannot become a grey horse. Dun and grey are two distinct coat colors determined by genetics. Dun horses have a specific dilution gene that gives them their characteristic coat color, while grey horses have a gene that causes their coat to progressively lighten with age. Once a horse is born with a dun coat, it will not change to a grey coat over time. **
