Assalamu alaikum Ustadh. Can you kindly explain if deeds like raising hands and Making dua every time before Studying or Making 3000 Istighfar everyday considered haram? Without believing that this number is special

Ustadh AbdulAziz al-Haqqan

If you think this is the sunnah, it turns to a bid'ah, but if you just generally do this and it varies then this is allowed walhamdulilah
