"If a person says: 'La ilaha illallahu wa Allahu Akbar (None has the right to be worshipped but Allah and Allah is the Most Great),'Allah says: 'My slave has spoken the truth; there is none worthy of worship except I, and I am the Most Great.' If a person says: La ilaha Illallah wahdahu (There is none worthy of worship except Allah alone), Allah says: 'My slave has spoken the truth; there is none worthy of worship except I, alone.' If he says, La ilaha illallahu la sharikalahu (There is none worthy of worship except Allah with no partner or associate),' Allah says: 'My slave has spoken the truth; there is none worthy of worship except I, with no partner or associate.' If he says: 'La illah illallah, lahul mulku wa lahul hamdu (There is none worthy of worship except Allah, all dominion is His and all praise is to Him),' Allah says: 'My slave has spoken the truth; there is none of worthy of worship except I, all dominion Mine and all praise is due to Me.' If he says: ' La illaha illallah, la hawla wa la quwwata illa billah (There is none worthy of worship and there is no power and no strength except with Allah),' Allah says: 'My slave has spoken then truth; there is none worthy of worship except I, and tehre is no power and no strength except with Me.' One of the narrators Abu Ishaq said: "Then Agharr (another narrator) said something that I did not understand. I said to Abu Jafar: 'What did he say?' He said: 'Whoever is blessed with (the ability to say) them (these words) at the time of death, the Fire will not touch him.'"

“A grandmother came to Abu Bakr Siddiq and asked him for her inheritance. Abu Bakr said to her: ‘You have nothing according to the Book of Allah, and I don’t know of anything for you according to the Book of Allah, and I don’t know of anything for you according to the Sunnah of the Messenger of Allah (saw). Go back until I ask the people.’ So he asked the people and Al-Mughirah bin Shu’bah said: ‘I was present with the Messenger of Allah (saw) and he gave her (the grandmother) one sixth.’ Abu Bakr said: ‘Is there anyone else with you (who will corroborate what you say)?’ Muhammad bin Maslamah Al-Ansari stood up and said something like what Mughirah bin Shu’bah had said. So Abu Bakr applied it in her case.”

“When the Messenger of Allah (saw) prayed Tahajjud at night, he would say: “Allahumma lakal-hamd, Anta nurus-samawati wal-ard wa man fihinna. Wa lakal-hamd, Anta qayyamus-samawati wal-ard wa man fihinna. Wa lakal-hamd, Anta malikus- samawati wal-ard wa man fihinna. Wa lakal-hamd, Antal-haqq, wa wa`duka haqq, wa liqa’uka haqq, wa qawluka haqq, wal-jannatu haqq, wan-naru haqq, was-sa`atu haqq, wan-nabiyyuna haqq, wa Muhammadun haqq. Allahumma laka aslamtu, wa bika amantu, wa `alaika tawakkaltu wa ilaika anabtu, wa bika khasamtu, wa ilaika hakamtu, faghfirli ma qaddamtu wa ma akhkhartu, wa ma asrartu wa ma a`lantu. Antal-muqaddimu wa Antal-muakhkhiru. La ilaha illa anta wa la ilaha ghairuka, wa la hawla wa la quwwata illa bika (O Allah, to you is praise, You are the Light of the heavens and the earth, and everyone therein. To You is praise, You are the Sustainer of the heavens and the earth, and everyone therein. To You is praise, You are the Sovereign of the heavens and the earth, and everyone therein. To You is praise, You are the Truth; Your promise is true, the meeting with You is true, Your saying is true, Paradise is true, the Fire is true, the Hour is true, the Prophets are true, and Muhammad (saws) is true. O Allah, to You have I submitted, in You I believe, in You have I put my trust, to You I turn in repentance, by Your help I argue, to You I refer my case, so forgive me for my past and future sins, what I have done in secret and what I have done openly. You are the One Who brings forward and puts back. None has the right to be worshipped but You, and there is none who has the right to be worshipped other than You. And there is no power and no strength except with You.”
Another chain that Ibn `Abbas narrated: “When the Messenger of Allah (saws) stood during the night for Tahajjud,” and he mentioned something similar.

Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "Allah ta'ala said to the self, 'Go forth.' It replied, 'I only go forth reluctantly.'"

Jabir ibn 'Abdullah reported that the Prophet, may Allah bless him and grant him peace, was asked, "How are you this morning?" He replied, "Well. Away from people who do not attend funerals or visit sick people."

‘Abdur Rahman bin Abi Laila (RAA) and ‘Zaid bin Arqam (RAA) used to recite four Takbirat when praying over the dead, but once he said it five times, so I asked him about it. He said to me, ‘The Messenger of Allah (P.B.U.H.) used to do so.’ Related by Muslim and the four Imams.

Jabir (RAA) narrated that the Messenger of Allah (P.B.U.H.) said, "I have offered my sacrifice here (at Mina) and all of Mina is a place for slaughtering, so sacrifice where you are staying (at Mina). And I have stopped here (at Arafat) and all of Arafat is a stopping place (for the Day of Arafat on the 9th of Dhul-Hijjah). And I have stood here, and all of Jam' (meaning al·Muzdalifah) is a place for standing.” Related by Muslim.

The Prophet (SAW) delayed (the 'Isha' prayer) one night till a great part of the night passed, then he went out and offered the prayer, and said, "This is the proper time for it; were it not that I would impose a burden on my followers." [Reported by Muslim].

Allah's Messenger (SAW) said, "Talking is not befitting during the Salat (prayer), for it (prayer) consists only of glorifying Allah, declaring His Greatness and the recitation of the Qur'an." [Reported by Muslim].

When Allah's Messenger (SAW) sat for at-Tashahhud, he placed his left hand on his left knee, and his right hand on his right knee, folded its fingers and pointed with his right index finger. [Reported by Muslim].

Whenever Allah's Messenger (SAW) finished his prayer, he used to say after asking Allah's forgiveness three times: "O Allah, You are as-Salam (One Free from every defect), and as-Salam (safety from every evil) is (sought) from You. Blessed are You, O Possessor of glory and honour." [Reported by Muslim].

The Prophet (SAW) used to deliver the Khutbah (religious talk, sermon) while standing. He (SAW) would then sit down and then stand up and deliver the Khutbah in a standing posture. So, whoever informs you that he [the Prophet (SAW)] delivered the Khutbah (religious talk, sermon) while sitting has definitely told a lie. [Reported by Muslim].

I learnt Surat Qaf (Chapter 50) from no other source than the tongue of Allah's Messenger (SAW) who used to recite it every Friday on the pulpit when he delivered the Khutbah (sermon) to the people." [Reported by Muslim].

When Allah decreed the Creation He pledged Himself by writing in His book which is laid down with Him: My mercy prevails over my wrath. It was related by Muslim (also by al-Bukhari, an-Nasa'i and Ibn Majah).
