3- Purifying pure water that is makrooh to use

1- Very hot water. This becomes not makrooh once cooled.

2- Very cold water. This becomes not makrooh once warmed.

The above waters are makrooh because it is difficult to wash the body parts thoroughly with them.

3- Water that has sat in the sun in a malleable-metal utensil [Made of a malleable metal, other than gold or silver, like iron, lead or copper] in a hot country on account of health reasons.

Al-Shafi'i said: "I am not against water sitting in the sun except from the viewpoint of health," and he attributed this to Umar ibn Al-Khattab who used to hate performing ghusl using water exposed to the sun and used to say that it can cause leprosy [Al-Nawawi said in Al-Majmu':

"The hadith is weak because it is narrated by Ibrahim ibn Muhammad ibn Abu Yahya".

They agreed that it is weak but Al-Shafi'i authenticated it].

Water sitting in the sun can be recognized by a thin film on its surface which is caused by a chemical reaction between the utensil's metal and the water in the sun.

Therefore, it is makrooh to use this water on one's body but not for purifying clothes.

Water sitting in the sun is no longer makrooh once it cools and the film disintegrates.

In mild climates, water sitting in the sun is not makrooh because the temperature is moderate.

4-Water from wells of people who have been cursed by Allah (G. B. H), except in dire need.

Ibn Umar (G. p. H) narrated: "When the Prophet (P. B. U. H) landed at

Al-Hijr (The land of Thamud) during the battle of Tabuk, he ordered his companions not to drink water from its well nor to reserve water from it.

They said: 'We have already kneaded the dough and filled our bags with its water. '

The Prophet (P. B. U. H) ordered them to throw away the dough and pour out the water.

[Al-Bukhari, Vol. 3, The Book of the Prophet (P. B. U. H) s, Chapter 19/3198].
