cheat

Assalamualaikum

I just can't understand.Sometimes the feeling of giving up is almost there.And sometimes I feel tired about all this.Tired to accept,tired to repeat the same thing,tired to fight,tired to talk.

How?Why?Until when?

I really don't understand people who can cheat other people about ALLAH's thing.
I just can't understand.

Don't they realize ALLAH is everywhere.
Or
the day when Izrail come is nothing for them?

Thinking of prophet Muhammad SAW.His patient.His love towards his people(umat).
Oh ALLAH.Please help me.Please help me to be strong,to be patient,to be not giving up now.
