Those who do not hold the sitting for rest

Khalid bin Ilyas, who is also called Iyas, and he is a weak narrator, narrated from Salih, the freed slave of al-Taw'amah, from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: "The Messenger of Allah (peace and blessings be upon him) used to rise in prayer on the balls of his feet."
And this is part of a hadith.

Sulayman al-A'mash (may Allah have mercy on him) said: I saw Umarah bin Umayr (may Allah have mercy on him) praying near the gates of Kindah. He bowed, then prostrated, and when he rose from the second prostration he stood straight up just as he was. When he finished with the salam, I mentioned the sitting for rest to him, and he said: Abd al-Rahman bin Yazid (may Allah have mercy on him) told me that he saw Abdullah bin Mas'ud (may Allah be pleased with him); in prayer he would rise straight up on his feet.
Al-A'mash (may Allah have mercy on him) said: I narrated this hadith to Ibrahim al-Nakha'i (may Allah have mercy on him), and he said: Abd al-Rahman bin Yazid (may Allah have mercy on him) also narrated to me that he saw Abdullah bin Mas'ud (may Allah be pleased with him) doing this. Then I narrated this hadith to Khaythamah bin Abd al-Rahman (may Allah have mercy on him), and he said: I saw Abdullah bin Umar (may Allah be pleased with them both); he would stand on his toes. Then I mentioned this to Muhammad bin Abdullah al-Thaqafi (may Allah have mercy on him), and he said: I saw Abd al-Rahman bin Abi Layla (may Allah have mercy on him); he too would stand on his toes. Then I mentioned this to Atiyyah al-Awfi (may Allah have mercy on him), and he said: I saw Ibn Umar (may Allah be pleased with them both), Ibn Abbas (may Allah be pleased with them both), Ibn al-Zubayr (may Allah be pleased with him) and Abu Sa'id al-Khudri (may Allah be pleased with him). All of them, in prayer, would rise (from the second prostration) straight up on their toes.

It is narrated from Abd al-Rahman bin Yazid (may Allah have mercy on him): I watched Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) and saw that he would rise (quickly) straight up on his toes, and in the first rak'ah, after finishing the prostrations, he would not sit.
Imam al-Bayhaqi (may Allah have mercy on him) said: The narration from Ibn Mas'ud is sahih (authentic), but following the Sunnah is better; and in the narration of al-Mughirah bin Hakim, Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) has explained that this is not a Sunnah of the prayer, and that he only did it because of an ailment. And Atiyyah al-Awfi is not used as evidence.
