When the Muslims arrived at Medina, they used to assemble for the prayer, and used to guess the time for it. During those days, the practice of Adhan for the prayers had not been introduced yet. Once they discussed this problem regarding the call for prayer. Some people suggested the use of a bell like the Christians, others proposed a trumpet like the horn used by the Jews, but `Umar was the first to suggest that a man should call (the people) for the prayer; so Allah's Apostle ordered Bilal to get up and pronounce the Adhan for prayers.

The Prophet pointed with his hand towards Yemen and said twice, "Faith is there," and then pointed towards the East, and said, "Verily, sternness and mercilessness are the qualities of those who are busy with their camels and pay no attention to their religion, where the two sides of the head of Satan will appear," namely, the tribes of Rabl'a and Muqar.

Allah's Apostle said, "When anyone of you stands for the prayers, Satan comes and puts him in doubts till he forgets how many rak`at he has prayed. So if this happens to anyone of you, he should perform two prostrations of Sahu while sitting.

The Prophet (saws) said: The best shroud is a lower garment and one which covers the whole body, and the best sacrifice is a horned ram.

Allah's Apostle said, "If anyone of you, when intending to have a sexual relation (sleep) with his wife, says: Bismillah, Allahumma jannibna ashShaitan, wa Jannib ash-Shaitana ma razaqtana, Satan would never harm that child, should it be ordained that they will have one. (Because of that sleep).

The Prophet said, "If anyone of you, when intending to have a sexual intercourse with his wife, says: 'Bismillah, Allahumma jannibna-sh-shaitan, wa jannibi-sh-shaitan ma razaqtana,' and if the couple are destined to have a child (out of that very sexual relation), then Satan will never be able to harm that child."

Allah's Apostle said, "When night falls (or it is evening), keep your children close to you for the devils spread out at that time. But when an hour of the night elapses, you can let them free. Close the doors and mention the Name of Allah, for Satan does not open a closed door."

The wife of the Prophet that she went to Allah's Apostle while he was in I`tikaf (staying in the mosque) during the last ten nights of the month of Ramadan. She spoke to him for an hour (a while) at night and then she got up to return home. The Prophet got up to accompany her, and when they reached the gate of the mosque opposite the dwelling place of Um Salama, the wife of the Prophet, two Ansari men passed by, and greeting Allah's Apostle , they quickly went ahead. Allah's Apostle said to them, "Do not be in a hurry She is Safiya, the daughter of Huyai." They said, "Subhan Allah! O Allah's Apostle (how dare we suspect you)." That was a great thing for both of them. The Prophet then said, "Satan runs in the body of Adam's son (i.e. man) as his blood circulates in it, and I was afraid that he (Satan) might insert an evil thought in your hearts."

Safiya, the wife of the Prophet told me that she went to Allah's Apostle to visit him in the mosque while he was in I`tikaf in the last ten days of Ramadan. She had a talk with him for a while, then she got up in order to return home. The Prophet accompanied her. When they reached the gate of the mosque, opposite the door of Um-Salama, two Ansari men were passing by and they greeted Allah's Apostle . He told them: Do not run away! And said, "She is (my wife) Safiya bint Huyai." Both of them said, "Subhan Allah, (How dare we think of any evil) O Allah's Apostle!" And they felt it. The Prophet said (to them), "Satan reaches everywhere in the human body as blood reaches in it, (everywhere in one's body). I was afraid lest Satan might insert an evil thought in your minds."

Gabriel did not come to the Prophet (for some time) and so one of the Quraish women said, "His Satan has deserted him." So came the Divine Revelation: "By the forenoon And by the night When it is still! Your Lord (O Muhammad) has neither Forsaken you Nor hated you." (93.1-3)

The son of Abu Said al-Khudri reported on the authority of his father that Allah's Messenger (may peace be upon him) said. When one of you yawns while engaged in prayer, he should try to restrain so far as it lies in his power, since it is the Satan that enter therein.

as below.

Narrated Abu Qatada:

The Prophet said, "A good dream is from Allah, and a bad or evil dream is from Satan; so if anyone of you has a bad dream of which he gets afraid, he should spit on his left side and should seek Refuge with Allah from its evil, for then it will not harm him."

I heard the Prophet saying, "A good dream is from Allah, and a bad dream is from Satan. So if anyone of you sees (in a dream) something he dislikes, when he gets up he should blow thrice (on his left side) and seek refuge with Allah from its evil for then it will not harm him."

I went to Sham (and asked. "Who is here?"), The people said, "Abu Ad-Darda." Abu Darda said, "Is the person whom Allah has protected against Satan, (as Allah's Apostle said) amongst you". The subnarrator, Mughira said that the person who was given Allah's Refuge through the tongue of the Prophet was `Ammar (bin Yasir).

(The Prophet) said, "O Allah! Bless our Sham and our Yemen." People said, "Our Najd as well." The Prophet again said, "O Allah! Bless our Sham and Yemen." They said again, "Our Najd as well." On that the Prophet said, "There will appear earthquakes and afflictions, and from there will come out the side of the head of Satan."

Once I went to him (the Prophet ) and he said, "By Allah in Whose Hands my life is (or probably said, 'By Allah, except Whom none has the right to be worshipped) whoever had camels or cows or sheep and did not pay their Zakat, those animals will be brought on the Day of Resurrection far bigger and fatter than before and they will tread him under their hooves, and will butt him with their horns, and (those animals will come in circle): When the last does its turn, the first will start again, and this punishment will go on till Allah has finished the judgments amongst the people."

(a companion of the Prophet and one of his cavalry men) "I heard Allah's Apostle saying, "A good dream is from Allah, and a bad dream is from Satan; so, if anyone of you had a bad dream which he disliked, then he should spit on his left and seek refuge with Allah from it, for it will not harm him."

Safiya bint (daughter of) Huyai came to the Prophet (in the mosque), and when she returned (home), the Prophet accompanied her. It happened that two men from the Ansar passed by them and the Prophet called them saying, "She is Safiya!" those two men said, "Subhan Allah!" The Prophet said, "Satan circulates in the human body as blood does."

The Prophet said, "Name yourselves after me (by my name), but do not call yourselves by my Kuniya, and whoever sees me in a dream, he surely sees me, for Satan cannot impersonate me (appear in my figure). And whoever intentionally ascribes something to me falsely, he will surely take his place in the (Hell) Fire.

Allah's Apostle said, "When the (upper) edge of the sun appears (in the morning), don't perform a prayer till the sun appears in full, and when the lower edge of the sun sets, don't perform a prayer till it sets completely. And you should not seek to pray at sunrise or sunset for the sun rises between two sides of the head of the devil (or Satan).

A drunk was brought to the Prophet and he ordered him to be beaten (lashed). Some of us beat him with our hands, and some with their shoes, and some with their garments (twisted in the form of a lash). When that drunk had left, a man said, "What is wrong with him? May Allah disgrace him!" Allah's Apostle said, "Do not help Satan against your (Muslim) brother."

The Prophet said, "If anyone of you sees a dream that he likes, then it is from Allah, and he should thank Allah for it and narrate it to others; but if he sees something else, i.e., a dream that he dislikes, then it is from Satan, and he should seek refuge with Allah from its evil, and he should not mention it to anybody, for it will not harm him."

Abu Bakr came to my house while two small Ansari girls were singing beside me the stories of the Ansar concerning the Day of Buath. And they were not singers. Abu Bakr said protestingly, "Musical instruments of Satan in the house of Allah's Apostle !" It happened on the `Id day and Allah's Apostle said, "O Abu Bakr! There is an `Id for every nation and this is our `Id."

Allah's Apostle (p.b.u.h) said, "Any person who takes a bath on Friday like the bath of Janaba and then goes for the prayer (in the first hour i.e. early), it is as if he had sacrificed a camel (in Allah's cause); and whoever goes in the second hour it is as if he had sacrificed a cow; and whoever goes in the third hour, then it is as if he had sacrificed a horned ram; and if one goes in the fourth hour, then it is as if he had sacrificed a hen; and whoever goes in the fifth hour then it is as if he had offered an egg. When the Imam comes out (i.e. starts delivering the Khutba), the angels present themselves to listen to the Khutba."

I heard Allah's Apostle saying, "If anyone of you saw a dream which he liked, then that was from Allah, and he should thank Allah for it and tell it to others; but if he saw something else, i.e, a dream which he did not like, then that is from Satan and he should seek refuge with Allah from it and should not tell it to anybody for it will not harm him."

The Prophet said, "Name yourselves with my name (use my name) but do not name yourselves with my Kunya name (i.e. Abul Qasim). And whoever sees me in a dream then surely he has seen me for Satan cannot impersonate me. And whoever tells a lie against me (intentionally), then (surely) let him occupy his seat in Hell-fire."
