Is Tadeel Arkan wajib in Jalsah and Qawmah
In the name of Allah, the most Beneficent, the most Merciful.
Answer
There is a difference in opinion in whether Tadeel Arkan is wajib or sunnah in the sitting between the two sajdahs (jalsah) and in the qawmah (the standing before going into ruku).
The strongest opinion and the most correct opinion is that it is wajib. (Raddul Muhtar p.157 v.2)
