Is it permissible for a man to extend both legs and sit on them when sitting between the two prostrations and during the tashahhud?

Question:
Honorable Shaykh, may Allah grant you success, he says: We have learned about iftirash and tawarruk during the tashahhud, so is the one who extends both legs and sits on them considered to be acting permissibly when sitting between the two prostrations, and likewise during the tashahhud?

Answer:
As for sitting between the two prostrations, it is reported from Ibn 'Umar that he used to do it. So if one does it sometimes, there is nothing wrong with it. If one does it sometimes, there is nothing wrong with it. As for making it a habit, no. But if one does it sometimes, there is nothing wrong with it. However, in the hadith they interpreted it with this sitting position, where one sits on his heels and extends his legs. But perhaps they mean making it a habit. As for doing it sometimes, it is fine.
