Tahaarat

Q: I am a mechanic and work with grease. Often the grease gets stuck to my hands and cannot be removed by any means and only comes out after many hours. How should I perform wudhu and perform salaah?

Q: I have some questions regarding laughing aloud (such that another person can here you) in salaah. I have seen multiple views and do not know which one is correct. 

1. Can you touch the Quraan afterwards (i.e. is it hadath or not)? 

2. For those who say it is for reprimanding the person, not hadath, according to them can you make tawaaf with that wudhu, or is tawaaf similar to salaah therefore tawaaf is invalid with that wudhu?

Q: If there is 20l of water and a person submerges their hand in the bucket, does the water became unsuitable for istinja and wudhu?

Q: Please assist in the scenario below: 

I went for a tooth extraction at 16H15 (Asr time sets in at 16H00 but I had not yet performed Asr). Just before Asr time ended I made Wudhu and prayed Asr with blood still coming out. The blood stopped during the time of Maghrib, so Maghrib Salah was no issue. 

My question is if I have to repeat Asr as I was not yet a Mazoor (as the bleeding was not found for a complete Salaah time) but I had to pray Asr with my mouth bleeding as time was running out.

Q: In our country, lizards are very common, and they poop everywhere. Is the poop of a house lizard impure? If a house lizard poop falls in water, does that water become impure? If someone steps on house lizard's poop with wet feet, does it make his feet impure?

Q: A scholar mentioned that it is fardh (obligatory) for two drops of water to fall from every hair and part of the skin that must be washed in wuḍūʾ. If this does not occur, it will be considered as masah (wiping) rather than proper washing. However, another scholar stated that as long as two drops of water fall from the entire limb, the wuḍūʾ will be valid, and it will be considered as washed. Which of these opinions is correct according to the Sharīʿah? 

Q: If a person is physically unable to lift his feet to wash them in the basin, is it permissible for him to perform masah (wiping) over the feet instead of washing? 

In such a case, if Ṣalāh is performed after doing masah instead of washing the feet, does the Ṣalāh need to be repeated?

Q: 

1. If wuḍuʾ is performed using a spray bottle, is the wuḍuʾ valid? 

2. With regard to the obligatory (farḍ) parts of the body that must be washed in wuḍuʾ, is it necessary for two drops of water to fall from each hair and part of the skin, or is it sufficient for two drops to fall from the entire organ (e.g., the face), even if only two drops fall in total after spraying water? 

Q: 

1. If one falls asleep without leaning on any structure, is the wudhu still valid? 

2. Also, what if you remember that you had a dream?
