Q: If water is available but a person is sick, will it be permissible for him to make tayammum?

Q: If you wear a garment for a short amount of time whilst you have your haidh, is the garment considered impure? No impurity has soiled the garment. You'd like to wear it again in a few days time, when you're are in a clean state, is that okay?

Q: Is there a way to differentiate between mazi and mani when I find a stain on my clothing after awaking from sleep?

Q: If there is dry impurity (such as pre-ejaculatory fluid) on a solid item (ex. a cellphone) and some wet hands touched it, then will the hands be considered impure? 

Q: My face is oily. When I am performing wudhu, some of the oil of my face gets onto my hands. Do I have to rub my hands with water to ensure that water gets underneath the oil and reach my skin?

Do I have to rub any part of my body if the oil of my face gets onto them (for example my forearms, my feet)?

In that same logic, if oil from a part of my face (the left part for example) get onto or mixes with the oil of another part of my face (the right part for example) do I have to rub that area with water (the right part of my face)? 

Q: If a dog licks you on clothes or body, what is the correct way to clean it?

There is a famous Hadith which mentions that if a dog licks a utensil, the latter should be cleaned 7 times with water and once with soil. Does this apply to just utensils or clothes/body as well?

Q: An old lady has been advised by a doctor to wear compression stockings on her legs for circulation. She doesn't have any wounds etc. on her legs. The stockings are from her knees and only the toes are open.

The stockings are very tight and she requires someone to put it on and remove it for her. Is it permissible for her to make masah over the stockings and only wash the toes for wudhu?

Q: Is pre-coital fluid considered najaasate ghaleeza or khafeefah?

Will it invalidate salaah?

Q: How big must a stone be for us to be able to use it for tayammum? Can it be a small stone that we roll around in our hands, or must it be big enough to cover the entire hand?

Q: If the person has access to water and isn’t ill and he can use it and suppose this person does the actions of tayammum, is it said that he did tayammum but it’s not valid or is it said that does not count as tayammum as water is present?
