Tahaarat

Q: I read somewhere that ground, wall made of bricks and trees become tahir (paak) if najasat (on them) becomes dry and there is no trace of it present?

Q: I am a 26 years old male. My right hand has got fractured and with plaster of Paris... Due to it I cannot use it and can't remove my upper clothes (shirt, etc.). I can go to the washroom on my own but I can't take a bath due to the injury. However I can only perform wudu (with masah on injured hand) and can wash lower part of my body i.e. legs and face and head. What is the ruling if ghusal gets obligatory upon me.... Should I make tayammum instead of ghusal or washing lower part of body, face and head and wet hand on upper body will suffice?

Q: Is it sunnah to cover your head when going to the toilet?

Q: I woke up after having a wet dream. I immediately made Ghusl and then remained awake for sometime during which I performed Salaat. I then urinated. A sticky, semen-like fluid came out with the urine. The urine was also very cloudy indicting the possible presence of semen therein. I therefore made Ghusl again.

1. Was it necessary for me to make Ghusl again after observing this about the urine?

2. Was the Salaat valid?

Q: Please explain the logic in this. A lizard fell on my mom, then my grandma told my mom to wash her head, then only can she perform Salah, otherwise it's not permissible, is that correct?

Q: Will handling haraam meat make ones's hands napaak?

Q: I am a mazoor suffering from urine incontinence and it is almost impossible for me to pray namaz without my clothes becoming soiled even after keeping a tissue paper in my underwear. I can't change my clothes everytime. Please help me as I am leaving out namaz because of this?

Q: Does ablution (wudhu) break when water comes out of the eyes due to an infection?

Q: If a dogs saliva touches your hand, not your clothes and it is washed off properly can you read salaah?

Q: Someone told my wife that after fullfiling the rights of the husband, when doing ghusal,  she should just pour 3 chulloo (handfuls) of water on her head. It is not compulsory to wash all her hair. Is she pure by pouring 3 chulloo (handfuls) i.e. little water on her hair. Will the ghusal will be valid or not?
