(One night) the Prophet woke up and said, "Subhan Allah ! How many treasures have been (disclosed) sent down! And how many afflictions have been descended! Who will go and wake the sleeping ladyoccupants up of these dwellings (for praying)?" (He meant by this his wives.) The Prophet added, "A well-dressed soul (person) in this world may be naked in the "Hereafter." `Umar said, "I asked the Prophet, 'Have you divorced your wives?' He said, 'No.' I said, 'Allahu Akbar.' "

Once Allah's Apostle prayed two rak`at (instead of four) and finished his prayer. Dhul-Yadain asked him whether the prayer had been reduced or whether he had forgotten. Allah's Apostle asked the people whether Dhul-Yadain was telling the truth. The people replied in the affirmative. Then Allah's Apostle stood up, offered the remaining two rak`at and then finished his prayer with Taslim and then said, "Allahu Akbar." He followed it with two prostrations like ordinary prostrations or a bit longer.

Once the Prophet (p.b.u.h) led the fear prayer and the people stood behind him. He said Takbir (Allahu-Akbar) and the people said the same. He bowed and some of them bowed. Then he prostrated and they also prostrated. Then he stood for the second rak`a and those who had prayed the first rak`a left and guarded their brothers. The second party joined him and performed bowing and prostration with him. All the people were in prayer but they were guarding one another during the prayer.

Anas said, 'When Allah's Apostle invaded Khaibar, we offered the Fajr prayer there (early in the morning) when it was still dark. The Prophet rode and Abu Talha rode too and I was riding behind Abu Talha. The Prophet passed through the lane of Khaibar quickly and my knee was touching the thigh of the Prophet . He uncovered his thigh and I saw the whiteness of the thigh of the Prophet. When he entered the town, he said, 'Allahu Akbar! Khaibar is ruined. Whenever we approach near a (hostile) nation (to fight) then evil will be the morning of those who have been warned.' He repeated this thrice. The people came out for their jobs and some of them said, 'Muhammad (has come).' (Some of our companions added, "With his army.") We conquered Khaibar, took the captives, and the booty was collected. Dihya came and said, 'O Allah's Prophet! Give me a slave girl from the captives.' The Prophet said, 'Go and take any slave girl.' He took Safiya bint Huyai. A man came to the Prophet and said, 'O Allah's Apostles! You gave Safiya bint Huyai to Dihya and she is the chief mistress of the tribes of Quraidha and An-Nadir and she befits none but you.' So the Prophet said, 'Bring him along with her.' So Dihya came with her and when the Prophet saw her, he said to Dihya, 'Take any slave girl other than her from the captives.' Anas added: The Prophet then manumitted her and married her." Thabit asked Anas, "O Abu Hamza! What did the Prophet pay her (as Mahr)?" He said, "Her self was her Mahr for he manumitted her and then married her." Anas added, "While on the way, Um Sulaim dressed her for marriage (ceremony) and at night she sent her as a bride to the Prophet . So the Prophet was a bridegroom and he said, 'Whoever has anything (food) should bring it.' He spread out a leather sheet (for the food) and some brought dates and others cooking butter. (I think he (Anas) mentioned As-Sawaq). So they prepared a dish of Hais (a kind of meal). And that was Walima (the marriage banquet) of Allah's Apostle ."

Whenever Allah's Apostle returned from a Ghazwa or Hajj or `Umra, he used to say, "Allahu Akbar," three times; whenever he went up a high place, he used to say, "La ilaha illal-lahu wahdahu la sharika lahu, lahu-l-mulk wa lahu-l-hamd, wa huwa'ala kulli Shai 'in qadir. Ayibuna ta'ibuna 'abiduna lirabbina hamidun. Sadaqa-l-lahu wa'dahu, wa nasara`Abdahu wa hazama-l-ahzaba wahdahu."

Whenever Allah's Apostle returned from a Ghazwa, Hajj or `Umra, he used to start (saying), "Allahu- Akbar," thrice and then he would say, "None has the right to be worshipped except Allah alone Who has no partners. To Him belongs the Kingdom, all praises are for Him, and He is able to do all things (i.e. Omnipotent). We are returning with repentance (to Allah) worshipping, prostrating, and praising our Lord. Allah has fulfilled His Promise, made His Slave victorious, and He (Alone) defeated the clans (of infidels) ."

When Allah's Apostle arrived in Mecca, he refused to enter the Ka`ba while there were idols in it. So he ordered that they be taken out. The pictures of the (Prophets) Abraham and Ishmael, holding arrows of divination in their hands, were carried out. The Prophet said, "May Allah ruin them (i.e. the infidels) for they knew very well that they (i.e. Abraham and Ishmael) never drew lots by these (divination arrows). Then the Prophet entered the Ka`ba and said. "Allahu Akbar" in all its directions and came out and not offer any prayer therein.

Allah's Apostle (p.b.u.h) offered the Fajr prayer when it was still dark, then he rode and said, 'Allah Akbar! Khaibar is ruined. When we approach near to a nation, the most unfortunate is the morning of those who have been warned." The people came out into the streets saying, "Muhammad and his army." Allah's Apostle vanquished them by force and their warriors were killed; the children and women were taken as captives. Safiya was taken by Dihya Al-Kalbi and later she belonged to Allah's Apostle go who married her and her Mahr was her manumission.

Abu Dawud said : This tradition has been narrated al-Zuhri from Abu Salamah b. ‘Abd al-Rahman on the authority of Abu Hurairah. It says: When he stood at the place of prayer, we waited for his utterance of takbir (Allah-u akbar).He went away and said : (remain) as you were.

Another version on the authority of Muhammad reporting from the Prophet (saws) says: He uttered takbir (Allah-u-Akbar) and then made a sign to the people, meaning "sit down". He then went away and took a bath. This tradition has also been narrated through a different chain. It says: The Messenger of Allah (saws) uttered takbir (Allah-u-akbar) in a prayer.

Abu Dawud said: Another version through a different chain says; The Prophet (May peace be upon him) uttered takbir (Allah-u akbar).

We were with the Prophet on a journey, and whenever we ascended a high place, we used to say, "Allahu Akbar." The Prophet said, "Don't trouble yourselves too much! You are not calling a deaf or an absent person, but you are calling One Who Hears, Sees, and is very near." Then he came to me while I was saying in my heart, "La hawla wala quwwatta illa billah (There is neither might nor power but with Allah)." He said, to me, "O `Abdullah bin Qais! Say, 'La hawla wala quwwata illa billah (There is neither might nor power but with Allah), for it is one of the treasures of Paradise." Or said, "Shall I tell you of it?"

I heard Al-Hajjaj saying on the pulpit, "The Sura in which Al-Baqara (the cow) is mentioned and the Sura in which the family of `Imran is mentioned and the Sura in which the women (An-Nisa) is mentioned." I mentioned this to Ibrahim, and he said, `Abdur-Rahman bin Yazid told me, 'I was with Ibn Mas`ud, when he did the Rami of the Jamrat-ul-Aqaba. He went down the middle of the valley, and when he came near the tree (which was near the Jamra) he stood opposite to it and threw seven small pebbles and said: 'Allahu-Akbar' on throwing every pebble.' Then he said, 'By Him, except Whom none has the right to be worshipped, here (at this place) stood the one on whom Surat-al-Baqra was revealed (i.e. Allah's Apostle).' "

Yahya related to me from Malik that Umara ibn Sayyad had heard Said ibn al Musayyab say about abiding good deeds that they were a slave's saying 'Allah is greater' (Allahu akbar) and 'Glory be to Allah' (Subahana'llah) and 'Praise be to Allah' (al-hamdu lillah) and 'There is no god but Allah and there is no power and no strength except by Allah.' (La ilaha illa'llah wa la hawla wa la quwwata illa bi'llah.)
