"شبب" - Translation from Arabic to English

I think it has to do with as my sister was released.
لا اظن ان هناك اي شبب لهذا الرحيل

Is there a particular reason...
أنا أسأل إذا كان هناك شبب قوي

Our friend here is all by himself.
صديقنا الذي هنا شبب هذا كله.

I gave her the what for.
-لقد منحتها لأي شبب
