Why make Dua when everything is pre written??

Re: Why make Dua when everything is pre written??

As-Salam Alaikum

How do we interpret the above Hadith?

I have found these short videos by Mufti Akmal, who is someone I learn from

Pakistan friendly link to above video: http://www.ytpak.com/?component=video&task=view&id=4sVCOGxXvdo Pakistani link: http://www.ytpak.com/?component=video&task=view&id=B7DptaxHsXo

The aqeedah i walk around with says pre destination can not be changed, and that is supported in the video?], but the wording of the Hadith is different. Surely the subject of the Hadith is only an apparent Qadr? I am confused, looks a long way down both ways on this tightrope
