Sadl And Qabd
Qabd is not one of the required actions of salat (hence the natural state of sadl). Sadl/qabd do not require ijma and tawatur because they belong to the optional part of salat. Please refer to the video below from 1:41:51 to 1:48:01 in order to understand the matter in principle. https://youtu.be/1Yg42iePNwo?t=6111
