The Messenger of Allah (ﷺ) enjoined killing the two black ones (snakes and scorpions) while praying.

"The Messenger of Allah (ﷺ) said: 'The tasbih is for men and clapping is for women.'"

"The Messenger of Allah (ﷺ) stood praying, and we heard him say: 'I seek refuge with Allah from you.' Then he said: 'I curse you with the curse of Allah (SWT),' three times and stretched out his hand as if to take something. When he finished praying we said: 'O Messenger of Allah, we heard you say something in your prayer that we have never heard you say before, and we saw you stretch out your hand.' He said: 'The enemy of Allah (SWT), Iblis, came with a brand of fire to throw it in my face, so I said: I seek refuge with Allah from you three times, then I wanted to take hold of him. By Allah (SWT), were it not for the prayer of our brother Sulaiman, he would have been tied up this morning for the children of Al-Madinah to play with him.'"

"We used to speak to each other during the prayer, saying whatever was necessary, at the time of the Messenger of Allah (ﷺ), until this verse was revealed: Guard strictly (five obligatory) As-Salawat (the prayers) especially the middle Salah (i.e. the best prayer- 'Asr). And stand before Allah with obedience (and do not speak to others during the Salah (prayers)), so we were commanded to be silent."

"I used to come to the Prophet (ﷺ) when he was praying, and I would greet him with Salam, he would return my greeting. Then I came to him when he was praying, and he did not return my greeting. When he said the Taslim, he pointed to the people and said: "Allah (SWT) has decreed that in the prayer you should not speak except to remember Allah (SWT), and it is not appropriate for you, and that you should stand before Allah (SWT) with obedience.'"

The Messenger of Allah (ﷺ) finished praying two rak'ahs,and Dhul-Yadain said to him: "Has the prayer been shortened or did you forget, O Messenger of Allah?" The Messenger of Allah (ﷺ) said: "Is Dhul-Yadain speaking the truth?" The people said: "Yes." So the Messenger of Allah (ﷺ) stood up and prayed two, then he said the takbir and prostrated as usual or longer than that. Then he raised his head, then he prostrated as usual or longer than that, then he sat up."

The Messenger of Allah (ﷺ) prayed Zuhr with two rak'ahs, then said the salam. They said: "Has the prayer been shortened?" So he stood up and prayed two rak'ahs, then he said the salam, then he prostrated twice.

"The Messenger of Allah (ﷺ) forgot and said the taslim after two rak'ahs. Dhul-Shimalain said to him: 'Has the prayer been shortened or did you forget, O Messenger of Allah (ﷺ)?' The Messenger of Allah (ﷺ) said: 'Is Dhul-Yadain speaking the truth?' They said: "Yes." So the Messenger of Allah (ﷺ) stood up and completed the prayer."

It was conveyed to him that the Messenger of Allah (ﷺ) prayed two rak'ahs, and Dhul-Shimalain said something similar to him. (One of the narrators Ibn Shihab said: "Sa'eed bin Al-Musayyab informed me of this hadith from Abu Hurairah." He said: "And Abu Salamah bin 'Abdur Rahman, Abu Bakr bin 'Abdur Rahman, abu Bakr bin 'Abdur Rahman bin Al-Harith and 'Ubaidullah bin 'Abdullah informed me."

The Messenger of Allah (ﷺ) prostrated twice after the salam on the day of Dhul-Yadain.

A similar report was narrated from Abu Hurairah from the Messenger of Allah (ﷺ).

"Ali bin Abi Talib prayed, and he said the takbir every time he went down and came up, in all movements of the prayer. 'Imran bin Husain said: 'This reminds me of the prayer of the Messenger of Allah (ﷺ).'"

"The Messenger of Allah (ﷺ) set out to bring about reconciliation among Banu 'Amr bin 'Awf. The time for prayer came, and the Mu'adhdhin went to Abu Bakr to tell him to gather the people and lead them in prayer. Then the Messenger of Allah (ﷺ) came and passed though the rows until he stood in the first row. The people started clapping to let Abu Bakr know that the Messenger of Allah (ﷺ) had come. Abu Bakr never used to turn around when he prayed, but when they clapped consistently he realized something must have happened while they were praying. So he turned around and saw the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) gestured to him to stay where he was. Abu Bakr raised his hands and praised and thanked Allah (SWT) for what the Messenger of Allah (ﷺ) had said. Then, he moved backwards, and the Messenger of Allah (ﷺ) went forward and prayed. When he finished, he said to Abu Bakr: 'What stopped you from continuing to pray when I gestured to you?' Abu Bakr, may Allah (SWT) be pleased with him, said: 'It was not appropriate for the son of Abu Quhafah to lead the Messenger of Allah (ﷺ) in prayer.' Then he said to the people: 'Why did you clap?' Clapping is for women.' Then he said: 'If you notice something when you are praying, say "SubhanAllah.'"

"Mu'aiqib told me that the Messenger of Allah (ﷺ) said: 'If you have to do that, then do it only once.'"

The Messenger of Allah (ﷺ) said: "What is the matter with people who lift their gaze to the sky when praying?" And he spoke sternly concerning that until he said: "They must stop that or they will certainly lose their eyesight."

A man from among the companions of the Prophet (ﷺ) told him that he heard the Messenger of Allah (ﷺ) say: 'If any one of you in praying, let him not lift his gaze to the sky, or his eyesight will be taken away.'"

"I heard Abu Al-Ahwas saying to us in a gathering with Ibn Al-Musayyab when Ibn Al-Musayyab was sitting there, that he had heard Abu Dharr say: The Messenger of Allah (ﷺ) said: "Allah (SWT) continues to look upon His slave while he is praying, so long as he does not turn away. If he turns his face away, He turns away from him."

A similar report was also narrated from 'Aishah, from the Prophet (ﷺ).

"Aishah said: 'Turning around during prayer is something that the Shaitan snatches from one's prayer.'"
