Allah's Messenger (SAW) said, "If one of you prays towards an object separating him from the people and someone tries to pass (between him and the object) in front of him, let him turn him away but if he refuses he should fight him for he is a devil." [Agreed upon].

that the Messenger of Allah (SAW) said: "Indeed Allah loves sneezing and He dislikes the yawn. So when one of you sneezes and says 'Al-Hamdulillah (All praise is due to Allah),' then it is a right due from every one who hears him to say: 'Yarhamukallah (May Allah have mercy upon you)' As for yawning then when one of you yawns let him suppress it as much as possible and not say: "Hah Hah' for that is only from Ash-Shaitan laughing at him."

If anyone amongst you intends to go to his wife he should say: In the name of Allah,0 Allah protect us against Satan and keep away the Satan from the one that you have bestowed upon us, and if He has ordained a male child for them, Satan will never be able to do any harm to him.

No child is born but he is pricked by the satan and he begins to weep because of the pricking of the satan except the son of Mary and his mother. Abu Huraira then said: You may recite if you so like (the verse):" I seek Thy protection for her and her offspring against satan the accursed" (iii. 36).

The Messenger of Allah (PBUH) said, "None of you should point at his brother with a weapon because he does not know that Satan may make it lose from his hand and, as a result, he may fall into a pit of Hell-fire (by accidentally killing him)."

[Al-Bukhari and Muslim].

The narration in Muslim is: Abul-Qasim (i.e., the Messenger of Allah) (PBUH) said, "He who points at his (Muslim) brother with a weapon is cursed by the angels even if the other person should be his real brother."

Allah’s Messenger (saw) said, “Satan comes to one of you in Salat and blows air in his bottom, so he imagines that he has realised air yet he did not. So if he gets that feeling he should not leave his prayer unless he hears the sound (of the air) or smells its odour.” [Reported by Al-Bazzar].

"When time draws near, the dreams of a believer will hardly ever fail to come true, and the most truthful of them in dreams will be the truest in speech among them. The dream of a Muslim is a portion among the forty-six portions of Prophet-hood. And dreams are of three types: The righteous dream which is good news from Allah, dreams in which the Shaithan frightens someone, and dreams about something that has happened to the man himself. So when one of you sees what he dislikes, then he should get up and spit, and not tell any of the people- he said:- and I like the fetters in a dream while I dislike the iron collar." And the interpretation of fetters is being firm in the religion".

The Messenger of Allah (PBUH) visited Umm Sa'ib (or Umm Musaiyyab) and asked her, "What ails you O Umm Sa'ib (or Umm Musaiyyab)? You are shivering." She replied: "It is a fever, may Allah not bless it!" He said to her, "Do not revile fever, for it cleanses out the sins of the sons of Adam in the same way that a furnace removes the dirt of iron."
