Ruling on tahur water heated by energy, by the sun, or by something impure
Is purification with water heated by energy, the sun, or something impure disliked or invalid?
Performing the ablution with heated water is permitted without any dislike, whether it was heated by fire or by the sun.
Purification is valid without dislike using water heated by fire or by something impure, so long as the smoke of the impurity has not altered it; sun-heated water is disliked in hot lands, a dislike on medical grounds.
Purification with heated water is valid; sun-heated water in a beaten-metal vessel in a hot land is disliked when used on the body while still hot, and water heated by fire is not disliked even if the fuel is impure.
Purifying with water heated by something impure, or by the sun when it grows very hot, is disliked, yet hadath is validly removed with it.
