Muzaara'ah partnership

Q: Zaid and John entered into a muzaara'ah partnership. Zaid will provide the land and seeds and John will do the planting, etc.

They have agreed that they both will have 50% ownership in the crop. They also agreed that John will then handle the sale of the crop, and they will then divide what is earned between them 50% each.

Is this partnership valid? Can John be made a wakeel to purchase seedlings as well? If the above partnership was incorrect, how should it be redone, as there are already seeds planted.

Please advise.

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.
