Based on the information provided and generally understood Islamic principles, ghusl, like wudu, is integrally linked to purification for worship but does not explicitly guarantee the removal of all sins.
Here's a breakdown:
- Ghusl is a requirement after a state of major ritual impurity, making it a prerequisite for performing acts of worship such as salah (prayer) and fasting.
- The reference states that "Yes, wudu washes away sins but we must be sincere while doing it." Since ghusl is a more comprehensive form of purification than wudu, it implies a similar potential for spiritual cleansing.
- The reference also states that "Ghusl is a requirement when one has reached a state of impurity so again it's a prerequisite for salah, fasting, and other forms of worship."
Therefore, while ghusl prepares a person for worship by removing ritual impurity, the act of sincerely performing ghusl, along with seeking forgiveness (istighfar) and having a firm intention to avoid sinning in the future, contributes to spiritual purification. It's not merely the physical act of washing, but the intention and sincerity behind it that plays a crucial role.
