Snow Water

وَمَا ذَابَ مِنَ الثَّلْجِ

Water melted from snow (Mā dhāba min al-thalj)

Ruling (Ḥukm): Snow, once it has melted (dhāba) into liquid water, is ṭāhir and muṭahhir like any other water, and is valid for wuḍūʾ and ghusl. The wording 'mā dhāba min al-thalj' (what has melted from snow) is deliberate: solid snow or ice cannot itself be used to complete wuḍūʾ by rubbing on the limbs unless it is melted or made to flow, because mere rubbing with a solid does not count as washing (ghasl) with water.

الْمِيَاهُ الَّتِي يَجُوزُ التَّطْهِيرُ بِهَا سَبْعَةُ مِيَاهٍ: (١) مَاءُ السَّمَاءِ، (٢) وَمَاءُ الْبَحْرِ، (٣) وَمَاءُ النَّهْرِ، (٤) وَمَاءُ الْبِئْرِ، (٥،٦) وَمَا ذَابَ مِنَ الثَّلْجِ وَمَاءُ الْبَرَدِ، (٧) وَمَاءُ الْعَيْنِ.

The waters with which purification (ṭahārah) is valid are seven: (1) sky/rain water, (2) sea water, (3) river water, (4) well water, (5–6) melted snow water and hail water, (7) spring water.
