Trimming the hair that exceeds the hairline

Q: When growing long hair, is it correct to trim the hair that exceeds the hairline, such as:

1. The hair around the ears, which covers the ears when the hair is combed downwards and curls up when the hair is combed backwards, is it correct to trim this hair by using a scissors or a machine around the ear?

2. The hair which exceeds the hairline at the back of the head, is it correct to trim this hair to the level of the hairline at the back?

3. The hair that exceeds the hairline on the sides of the back of the head, is it correct to pull these hairs to one side with a comb, and trim off whatever exceeds the hairline?

4. The hair of the sideburns from the top of the ear till the middle of the ear, if the sideburns become too long and look untidy?

Disciplining oneself to perform salaah

Q: I don't pray salah because I find it very difficult. I can't manage time nor do I have good health. I also have to do wudu every time I pray and change clothes. Praying salah involves so much, I struggle with it very much. I'm amazed how some people can pray salah 5 times per day without struggle or any problems. Please give me some advise how to manage time, how to discipline myself to pray salah and how to make prayer most important thing in my life.

Musallee looking inside the Quraan during Taraweeh and correcting the Imaam

Q: Please advise with regard to the following:

Is it permissible for a Musallee to look inside the Quraan during Taraweeh? If not, is there any social occasion in which it would be permissible?

If we are 3 people in our Taraaweeh Jamaat - the Imaam and one Musallee is a Hafiz, but their dhor is not so good and plan to improve it by performing Taraaweeh - will it be permissible for the Musallee to look into the Quraan during the Salah?
