The key to prayer is purification; its beginning is takbir and its end is taslim.

The Prophet went out and offered the funeral prayer for the martyrs of the (battle of) Uhud and then ascended the pulpit and said, "I am your predecessor and I am a witness against you. By Allah, I am now looking at my Tank-lake (Al-Kauthar) and I have been given the keys of the treasures of the earth (or the keys of the earth). By Allah! I am not afraid that after me you will worship others besides Allah, but I am afraid that you will start competing for (the pleasures of) this world."

One day the Prophet went out and offered the (funeral) prayer for the people (i.e. martyrs) of Uhud as he used to offer a funeral prayer for any dead person, and then (after returning) he ascended the pulpit and said, "I am your predecessor before you, and I am a witness upon you, and I am looking at my Tank just now, and I have been given the keys of the treasures of the world (or the keys of the world). By Allah, I am not afraid that you will worship others besides Allah after me, but I am afraid that you will compete with each other for (the pleasures of) this world."

The Prophet (saws) said: The key of prayer is purification; takbir (saying "Allah is most great") makes (all acts which break prayer) unlawful and taslim (uttering the salutation) makes (all such acts) lawful.

Once the Prophet went out and offered the funeral prayers for the martyrs of Uhud, and then went to the pulpit and said, "I am a predecessor for you and I am a witness for you: and by Allah, I am looking at my Fount just now, and the keys of the treasures of the earth (or the keys of the earth) have been given to me: and by Allah, I am not afraid that you will worship others besides Allah after me, but I am afraid that you will strive and struggle against each other over these treasures of the world."

One day the Prophet went out and offered the funeral prayers of the martyrs of Uhud and then went up the pulpit and said, "I will pave the way for you as your predecessor and will be a witness on you. By Allah! I see my Fount (Kauthar) just now and I have been given the keys of all the treasures of the earth (or the keys of the earth). By Allah! I am not afraid that you will worship others along with Allah after my death, but I am afraid that you will fight with one another for the worldly things."

The Prophet once came out and offered the funeral prayer for the martyrs of Uhud, and proceeded to the pulpit and said, "I shall be your predecessor and a witness on you, and I am really looking at my sacred Fount now, and no doubt, I have been given the keys of the treasures of the world. By Allah, I am not afraid that you will worship others along with Allah, but I am afraid that you will envy and fight one another for worldly fortunes."

The Prophet arrived (at Mecca) in the year of the Conquest (of Mecca) while Usama was riding behind him on (his she-camel)'. Al-Qaswa.' Bilal and `Uthman bin Talha were accompanying him. When he made his she-camel kneel down near the Ka`ba, he said to `Uthman, "Get us the key (of the Ka`ba). He brought the key to him and opened the gate (of the Ka`ba), for him. The Prophet, Usama, Bilal and `Uthman (bin Talha) entered the Ka`ba and then closed the gate behind them (from inside). The Prophet stayed there for a long period and then came out. The people rushed to get in, but I went in before them and found Bilal standing behind the gate, and I said to him, "Where did the Prophet pray?" He said, "He prayed between those two front pillars." The Ka`ba was built on six pillars, arranged in two rows, and he prayed between the two pillars of the front row leaving the gate of the Ka`ba at his back and facing (in prayer) the wall which faces one when one enters the Ka`ba. Between him and that wall (was the distance of about three cubits). But I forgot to ask Bilal about the number of rak`at the Prophet had prayed. There was a red piece of marble at the place where he (i.e. the Prophet) had offered the prayer.

Once Allah's Apostle led us in prayer and then (after finishing it) ascended the pulpit and pointed with his hand towards the Qibla of the mosque and said, "While I was leading you in prayer, both Paradise and Hell were displayed in front of me in the direction of this wall. I had never seen a better thing (than Paradise) and a worse thing (than Hell) as I have seen today, I had never seen a better thing and a worse thing as I have seen today."

AbuSalih reported on the authority of some Companions of the Prophet (saws): The Prophet (saws) said to a person: what do you say in prayer?

He replied: I first recite tashahhud (supplication recited in sitting position), and then I say: O Allah, I ask Thee for Paradise, and I seek refuge in Thee from Hell-Fire, but I do not understand your sound and the sound of Mu'adh (what you say or he says in prayer). The Prophet (saws) said: We too go around it (paradise and Hell-fire).

The Prophet said, "I have been given the keys of eloquent speech and given victory with awe (cast into the hearts of the enemy), and while I was sleeping last night, the keys of the treasures of the earth were brought to me till they were put in my hand." Abu Huraira added: Allah's Apostle left (this world) and now you people are carrying those treasures from place to place.

The Prophet said, "Whoever believes in Allah and His Apostle, offer prayer perfectly and fasts the month of Ramadan, will rightfully be granted Paradise by Allah, no matter whether he fights in Allah's Cause or remains in the land where he is born." The people said, "O Allah's Apostle ! Shall we acquaint the people with the is good news?" He said, "Paradise has one-hundred grades which Allah has reserved for the Mujahidin who fight in His Cause, and the distance between each of two grades is like the distance between the Heaven and the Earth. So, when you ask Allah (for something), ask for Al-firdaus which is the best and highest part of Paradise." (i.e. The sub-narrator added, "I think the Prophet also said, 'Above it (i.e. Al-Firdaus) is the Throne of Beneficent (i.e. Allah), and from it originate the rivers of Paradise.")

I heard the Messenger of Allah (saws) say: Allah is pleased with a shepherd of goats who calls to prayer at the peak of a mountain, and offers prayer, Allah, the Exalted, says: Look at this servant of Mine; he calls to prayer and offers it and he fears Me. So I forgive him and admit him to paradise.

A man said to the Prophet "Tell me of such a deed as will make me enter Paradise." The people said, "What is the matter with him? What is the matter with him?" The Prophet said, "He has something to ask. (What he needs greatly) The Prophet said: (In order to enter Paradise) you should worship Allah and do not ascribe any partners to Him, offer prayer perfectly, pay the Zakat and keep good relations with your Kith and kin." (See Hadith No. 12, Vol 8).

The Prophet said, "Allah will prepare for him who goes to the mosque (every) morning and in the afternoon (for the congregational prayer) an honorable place in Paradise with good hospitality for (what he has done) every morning and afternoon goings.

The Prophet led us in prayer and then went up to the pulpit and beckoned with both hands towards the Qibla of the mosque and then said, "When I started leading you in prayer, I saw the display of Paradise and Hell on the wall of the mosque (facing the Qibla). I never saw good and bad as I have seen today." He repeated the last statement thrice.

Malik related to me from Abdullah ibn Abi Bakr that Abu Talha al- Ansari was praying in his garden when a wild pigeon flew in and began to fly to and fro trying to find a way out. The sight was pleasing to him and he let his eyes follow the bird for a time and then he went back to his prayer but could not remember how much he had prayed. He said, "A trial has befallen me in this property of mine." So he came to the Messenger of Allah, may Allah bless him and grant him peace, and mentioned the trial that had happened to him in his garden and said, "Messenger of Allah, it is a sadaqa for Allah, so dispose of it wherever you wish."

A man from the Companions of the Prophet (saws) passed by ravine containing a small spring of thirst quenching water, so he was amazed by how pleasant it was. So he said: 'I should leave the people and stay in this ravine. But I will not do it until I seek permission from the Messenger of Allah (saws).' So he mentioned that to the Messenger of Allah (saws) and he said: 'Do not do so. For indeed one of you standing in the cause of Allah is more virtuous that his Salat in his house for seventy years. Do you not love that Allah forgive your sins and admit you into Paradise ? Then fight in the cause of Allah, for whoever fights in Allah's cause for the time it takes for two milkings of a camel, then Paradise is obligatory for him.'"

[Abu 'Eisa said:] This Hadith is Hasan.

At the time of the Fajr prayer the Prophet asked Bilal, "Tell me of the best deed you did after embracing Islam, for I heard your footsteps in front of me in Paradise." Bilal replied, "I did not do anything worth mentioning except that whenever I performed ablution during the day or night, I prayed after that ablution as much as was written for me."

The Prophet said, "The keys of the Unseen are five." And then he recited: 'Verily, the knowledge of the Hour is with Allah (alone).' (31.34)
