Assalamu alaikum ustadh. Is raising hands when making dua after Qiyam Al Layl or during the 3rd part of the night or after Asr on Friday (blessed hour) a bidah ?

Ustadh AbdulAziz al-Haqqan

Make du'a' in the salah may Allah reward you, as for general du'a' yes you can raise your hands and face the qiblah.
