The Messenger of Allah (ﷺ) said, "How is it that some people raise their eyes towards the sky during As-Salat (the prayer)?"

I asked the Messenger of Allah (ﷺ) about random looks in Salat (prayer), and he replied, "It is something which Satan snatches from the slave's Salat."[Al-Bukhari].

The Messenger of Allah (ﷺ) said to me, "Beware of looking around in Salat (prayer), because random looks in Salat are a cause of destruction. If there should be no help from it, it is permissible in the voluntary and not in obligatory Salat."[At-Tirmidhi].

I heard the Messenger of Allah (ﷺ) saying: "Do not offer Salat (prayer) facing the graves and do not sit on them."[Muslim].

The Messenger of Allah (ﷺ) said, "If the person who passes in front of a praying person, realizes the enormity of the sinfulness of this act, it will have been better for him to wait forty than to pass in front of him."[Al-Bukhari and Muslim].[The narrator was not sure whether the Prophet (ﷺ) said forty days, months or years.]

Juwairiyah bint Al-Harith (May Allah be pleased with her), the Mother of the Believers, said that the Prophet (ﷺ) visited her on a Friday and she was observing fast. He asked, "Did you observe fast yesterday?" She said, "No." He asked, "Do you intend to observe fast tomorrow?" She said, "No." He said, "In that case, give up your fast today."[Al-Bukhari].

The Prophet (ﷺ) prohibited observing continuous voluntary fasts beyond one day.[Al-Bukhari and Muslim].

The Messenger of Allah (ﷺ) said, "It is much better for one of you to sit on a live coal, which will burn his clothes and get to his skin than to sit on a grave."[Muslim].
