This is an example of using the Reader Monad for Dependency Injection using LINQ in C#. I learned about this from Tony Morris and Rúnar Bjarnason's video here: http://www.youtube.com/watch?v=ECPGTUa1WAI To figure out the (slightly weird) SelectMany peculiarities I found http://mikehadlow.blogspot.com/2011/01/monads-in-c-4-linq-loves-monads.html
public static class ReaderMonadExt
{
public static Func<T, C> SelectMany<T, A, B, C>(this Func<T, A> t_a, Func<A, Func<T, B>> a_t_b, Func<A, B, C> ab_c)
{
return t =>
{
var a = t_a(t);
return ab_c(a, a_t_b(a)(t));
};
}

Some Tips for Raising Muslim Children by Mufti Ismail Menk

  1. Praise your child, even if they get 4/10 in an exam, praise your child in front of others.

  2. Never make your child feel that he or she is useless. Never favour one child over the other.

  3. Every time you speak with your children, speak with respect, say “Jazakallahu khair ”, etc. Don’t use slang such as ‘gimme’, instead say ‘please give me’; use clear words, be polite and never swear.

  4. You need to bear in mind when your child is young that he or she is just a child, don’t take away their playing time by treating them like adults. If you do this, they will rebel in life.
