His father (Ibn ‘Umar) said: “One of the sunnahs of the prayer is to hold the right foot upright and point its toes toward the Qiblah, and to sit on the left foot.”
“I said: ‘I am going to watch the Messenger of Allah (ﷺ) and see how he prays.’ The Messenger of Allah (ﷺ) stood up and faced the Qiblah, then he raised his hands until they were in level with his ears, then he held his left hand with his right. When he wanted to bow, he raised them (his hands) likewise, then placed his hands on his knees. When he raised his head from bowing, he raised them (his hands) likewise. When he prostrated he put his hands in the same position in relation to his head, then he sat up and lay his left foot on the ground. He placed his left hand on his left thigh and his right elbow on his right thigh, and made a circle with two of his fingers. And I saw him doing like this”- Bishr (one of the narrators) pointed with the forefinger of his right hand and made a circle with the thumb and middle finger.
“O Shabath! Do not spit in front of you, for the Messenger of Allah (ﷺ) used to forbid that, and he said: ‘When a man stands up to perform prayer, Allah turns His Face towards him until he turns away or he commits an evil Hadath.’”* * In Injah Al-Hajah, ‘Abdul-Ghani Dehlawi said: “Meaning he does a matter that negates the Khushu'(submissiveness) and attentiveness of his prayer. Or, the meaning of Hadath is invalidating the ablution. The only reason that he described it as ‘evil’ is because in most cases, its occurrence during prayer is from Shaitan.”
