Sunnats after Jumuah Salaah

Q: A recent WhatsApp message circulated by a Mufti has created some confusion regarding the status of the Sunnah Rakats after the Jumuah Salaat. According to the message, the four rakats after Jumuah are Muakkadah whilst the other two are Ghair Muakkadah. The question is that we were always taught and considered that there are 6 Rakats (4+2) of Sunnah Muakkadah. What is the status of the Sunnah Salaats after Jumuah Salaat?

Dying the hair black

Q: I am a twenty years old. Since January I have a disease. Now I am recovering. My question is that this disease has caused my hair to turn white before age. I know that it is haraam to pluck white hair and also that one falls in Allah's eyes by doing such deeds. But I have also heard that young muslims can even dye their hair black if they wish. I want to ask that is it permissible to pluck such white hair that are growing before age and are a result of a temporary disease?

Are the deceased aware of the happenings of this world?

Q:

1. Can a dead Muslim feel the feelings of his close relatives after his death? i.e their sorrows, weeping, happiness and they are remembering him or not after him/her? The soul of a good Muslim can come in the world to know about his family? I heard that the soul come to the place where he/she died for forty days. And they come if there is halwa or some good thing cooked like chicken and if there is lentil like masur dal then they go away, I heard that it is common concept of deobandis and bralvis.

2. Do we feel or see the souls of our close relatives? What is the reality of dreams about dead ones?

3. Dead can not hear us? but most muftis say that they can hear due to prophet saw used to say salam to them.
