Q: After making wudhu in the morning and performing my Fajr salaah, I noticed that there was still some dirt around my eyes. Will this nullify my wudhu or salaah?

Q: What is the Sunnah method of holding a miswaak to use it?

Q: I would like to know if when a person is on dialysis (haemodialysis) where your blood comes out goes into a machine gets filtered an returns to your body. Does this break your wudhu?

Q: I have a graze on my front private part, a bit of skin came off. There is now a build up of water\pus there. The water\pus stayed within the wound and I prayed Asr and Maghrib with the same wudu. I prayed Esha late and when I checked the wound I noticed the water/pus had flowed beyond the wound. I can't be sure if it soaked through my underwear and onto my trousers. I just changed my underwear but wore same trousers to pray. I can't be fully sure it soaked through. I just changed them due to precaution. I have these doubts always.

Q: During wudhu, whilst washing the arms, is it also fardh to include washing the hands too, or is washing the the arm from the wrist to the elbow sufficient as hands have already been washed previously at the beginning?
