[Machine] To attach his buttocks to the ground and stand up on his legs and place his hands on the ground and said in another place, "Sitting on both buttocks, with his thighs in the same position as the sitting of a dog or a wolf." The sheikh said, "This type of sitting is not what we have narrated from Ibn Abbas and Ibn Umar, and this is prohibited. We have narrated from Ibn Abbas and Ibn Umar that it is a recommended practice. As for the narration of Abu Al-Jawza'a from Aisha from the Prophet ﷺ, that he used to forbid sitting on one's heels, and he used to stretch out his left leg and keep his right leg upright, it can be understood that this is applicable in the final tashahhud, and it does not contradict what we have narrated from Ibn Abbas and Ibn Umar about sitting between the two prostrations. And Allah knows best.
