use of perfect hello, i have a really big problem with the negativation of arabic sentenses in perfect, so, how do i negate the sentense "كنت قد كتنت كتابا في الشتاء" > like this: "كنت لم افعل؟" or لم اكن افعل؟ and what about "اكون قد فعلت" is it "كنت لا افعل" or "لا اكون قد فعلت" ? and when do i use which form? that's a bit difficult for me, thanks for help :)
