Wudhu

Q: Is it necessary to rub the eyes when making wudhu?  If a little dirt is stuck in the corner of the eye, is wudhu accepted?

Q: Will my wudhu or ghusal be accepted if I have instant henna/mendhi on my hands. If not, why?

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: 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?

Q: I have a problem of bleeding gums. The bleeding occurs anytime during the day or night. Sometimes I am unaware of it and other times I spit and rinse my mouth when I get taste in my mouth. My questions are 

1. How do I maintain wudu in this state? This is causing me to perform wudu multiple times sometimes. 

2. How do I fast? I try my best to rinse my mouth continuously when I am awake to avoid swallowing. But I am worried about when I am asleep and don't know if I swallowed or not. 

3. If my fasts are becoming invalid what is the kaffarah I need to pay? Should I pay for all the previous Ramadans because I am not sure about when I started suffering from the bleeding gums problem.
