i see that you need to know the meaning of the words , that is fine but arabic laguage does'nt work like this . for words translation ther is a way but in the conbinatin of sentences you can do better with fewer words and it sounds more pleasant and stroger meaning . any way my freind here do mostly a good translation , i recommend you to follow his advices . good luck
