Here's what we know:
* Quran: There are a few verses that mention white horses, but they are usually part of descriptions of paradise or the Day of Judgement. For example, in Surah al-Qasas (28:31), the Prophet Musa (Moses) is told to ride a white horse while fleeing Egypt. This could be seen as a symbol of divine intervention and protection.
* Hadith: The Hadith, or sayings of the Prophet Muhammad, also mention white horses in a few instances. For example, one Hadith describes the Prophet's steed as white, but this is not interpreted as a specific symbol.
* Some interpretations: In some Islamic interpretations, the white horse can be seen as a symbol of purity, righteousness, and divine guidance. This is based on the general association of white with purity and goodness.
However, it's important to note that the "White Horse" does not hold a widespread or specific meaning in mainstream Islam. It's not a symbol that is commonly used or discussed in Islamic theology or practice.
It's also important to avoid drawing connections between Islamic symbolism and other religious traditions or mythology. The "White Horse" has significance in other belief systems (such as Christianity), and it's best to keep those separate from Islamic interpretations.
