[Machine] I heard Abu Humaid Al-Sa'idi speaking about ten companions of the Prophet ﷺ among them Abu Qatada. Abu Humaid said, "I know the prayer of the Messenger of Allah ﷺ very well," and then he mentioned the hadith in detail until he reached the part where, during the prostration, the one who offers the prayer extends his left leg and sits on his left hip. They all said, "Yes, this is how the Messenger of Allah ﷺ used to pray," and this narration specifically refers to the final Tashahhud, but it does not mention the sitting posture in the first Tashahhud. Both Ibn Halhala and Muhammad bin Amr have preserved this narration. With the help of Allah, and as for the hadith of Abu Al-Jawzah from Aisha regarding the prayer of the Messenger of Allah ﷺ , he used to say the greetings in both units of prayer and he used to extend his left leg and keep his right leg upright. He used to discourage placing one foot over the other, and the hadith of Wail bin Hujr in the prayer of the Prophet ﷺ where he sat and extended his left leg, one of them is mentioned in the final Tashahhud and the other is mentioned in the first Tashahhud, relying on the Hadith of Abu Humaid Al-Sa'idi and his companions.
