The Prophet used to offer the prayer earlier if it was very cold; and if it was very hot he used to delay the prayer, i.e. the Jumua prayer.

One day while Allah's Apostle was sitting with the people, a man came to him walking and said, "O Allah's Apostle. What is Belief?" The Prophet said, "Belief is to believe in Allah, His Angels, His Books, His Apostles, and the meeting with Him, and to believe in the Resurrection." The man asked, "O Allah's Apostle What is Islam?" The Prophet replied, "Islam is to worship Allah and not worship anything besides Him, to offer prayers perfectly, to pay the (compulsory) charity i.e. Zakat and to fast the month of Ramadan." The man again asked, "O Allah's Apostle What is Ihsan (i.e. perfection or Benevolence)?" The Prophet said, "Ihsan is to worship Allah as if you see Him, and if you do not achieve this state of devotion, then (take it for granted that) Allah sees you." The man further asked, "O Allah's Apostle When will the Hour be established?" The Prophet replied, "The one who is asked about it does not know more than the questioner does, but I will describe to you its portents. When the lady slave gives birth to her mistress, that will be of its portents; when the bare-footed naked people become the chiefs of the people, that will be of its portents. The Hour is one of five things which nobody knows except Allah. Verily, the knowledge of the Hour is with Allah (alone). He sends down the rain, and knows that which is in the wombs." (31.34) Then the man left. The Prophet said, "Call him back to me." They went to call him back but could not see him. The Prophet said, "That was Gabriel who came to teach the people their religion." (See Hadith No. 47 Vol 1)

Muhammad ibn Yahya ibn Habban asked Abdullah ibn Abdullah ibn Umar about the reason for Ibn Umar's performing ablution for every prayer, whether he was with or without ablution.

He replied: Asma', daughter of Zayd ibn al-Khattab, reported to me that Abdullah ibn Hanzalah ibn AbuAmir narrated to her that the Messenger of Allah (saws) was earlier commanded to perform ablution for every prayer whether or not he was with ablution.

When it became a burden for him, he was ordered to use tooth-stick for every prayer. As Ibn Umar thought that he had the strength (to perform the ablution for every prayer), he did not give up performing ablution for every prayer.

Abu Dawud said: Ibrahim b. Sa'd narrated this tradition on the authority of Muhammad b. Ishaq, and there he mentions the name of 'Ubaid Allah b. 'Abd Allah (instead of 'Abd Allah b. 'Abd Allah b. 'Umar)

The Prophet said, "The prayer in congregation is twenty five times superior to the prayer offered by person alone."

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to say, "Someone who only remembers that he has forgotten a prayer when he is praying the next prayer behind an imam, should pray the prayer he has forgotten after the imam has said the taslim, and then pray the other one again."

The Prophet led us in a prayer and then got up on the pulpit and said, "In your prayer and bowing, I certainly see you from my back as I see you (while looking at you.)"

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."

When the Prophet went out for the `Umra in the month of Dhal-Qa'da, the people of Mecca did not allow him to enter Mecca till he agreed to conclude a peace treaty with them by virtue of which he would stay in Mecca for three days only (in the following year). When the agreement was being written, the Muslims wrote: "This is the peace treaty, which Muhammad, Apostle of Allah has concluded." The infidels said (to the Prophet), "We do not agree with you on this, for if we knew that you are Apostle of Allah we would not have prevented you for anything (i.e. entering Mecca, etc.), but you are Muhammad, the son of `Abdullah." Then he said to `Ali, "Erase (the name of) 'Apostle of Allah'." `Ali said, "No, by Allah, I will never erase you (i.e. your name)." Then Allah's Apostle took the writing sheet...and he did not know a better writing..and he wrote or got it the following written! "This is the peace treaty which Muhammad, the son of `Abdullah, has concluded: "Muhammad should not bring arms into Mecca except sheathed swords, and should not take with him any person of the people of Mecca even if such a person wanted to follow him, and if any of his companions wants to stay in Mecca, he should not forbid him." (In the next year) when the Prophet entered Mecca and the allowed period of stay elapsed, the infidels came to `Ali and said "Tell your companion (Muhammad) to go out, as the allowed period of his stay has finished." So the Prophet departed (from Mecca) and the daughter of Hamza followed him shouting "O Uncle, O Uncle!" `Ali took her by the hand and said to Fatima, "Take the daughter of your uncle." So she made her ride (on her horse). (When they reached Medina) `Ali, Zaid and Ja`far quarreled about her. `Ali said, "I took her for she is the daughter of my uncle." Ja`far said, "She is the daughter of my uncle and her aunt is my wife." Zaid said, "She is the daughter of my brother." On that, the Prophet gave her to her aunt and said, "The aunt is of the same status as the mother." He then said to `Ali, "You are from me, and I am from you," and said to Ja`far, "You resemble me in appearance and character," and said to Zaid, "You are our brother and our freed slave." `Ali said to the Prophet 'Won't you marry the daughter of Hamza?" The Prophet said, "She is the daughter of my foster brother."

I used to greet the Prophet while he was in prayer and he would return my greeting, but when we returned (from Ethiopia) I greeted the Prophet (while he was praying) but he did not return the greeting, and (after finishing the prayer) he said, "In the prayer one is occupied (with a more serious matter)."

Allah's Apostle said, "Whoever could get one rak`a of a prayer, (in its proper time) he has got the prayer."

I asked Allah's Apostle about looking hither and thither in prayer. He replied, "It is a way of stealing by which Satan takes away (a portion) from the prayer of a person."

Urwa bin Az-Zubair and I entered the Mosque (of the Prophet) and saw `Abdullah bin `Umar sitting near the dwelling place of Aisha and some people were offering the Duha prayer. We asked him about their prayer and he replied that it was a heresy. He (Urwa) then asked him how many times the Prophet had performed `Umra. He replied, 'Four times; one of them was in the month of Rajab." We disliked to contradict him. Then we heard `Aisha, the Mother of faithful believers cleaning her teeth with Siwak in the dwelling place. 'Urwa said, "O Mother! O Mother of the believers! Don't you hear what Abu `Abdur Rahman is saying?" She said, "What does he say?" 'Urwa said, "He says that Allah's Apostle performed four `Umra and one of them was in the month of Rajab." `Aisha said, "May Allah be merciful to Abu `Abdur Rahman! The Prophet did not perform any `Umra except that he was with him, and he never performed any `Umra in Rajab."

Sa'id ibn al-Musayyab said: An Ansari was breathing his last. He said: I narrate to you a tradition, and I narrate it with the intention of getting a reward from Allah.

I heard the Messenger of Allah (saws) say: If any one of you performs ablution and performs it very well, and goes out for prayer, he does not take his right step but Allah records a good work (or blessing) for him, and he does not take his left step but Allah remits one sin from him. Any one of you may reside near the mosque or far from it; if he comes to the mosque and prays in congregation, he will be forgiven (by Allah).

If he comes to the mosque while the people had prayed in part, and the prayer remained in part, and he prays in congregation the part he joined, and completed the part he had missed, he will enjoy similarly (i.e. he will be forgiven). If he comes to the mosque when the people had finished prayer, he will enjoy the same.
