"Before the tashahhud was enjoined, when we prayed we used to say: 'Peace (As-Salam) be upon Allah (SWT), pace be upon Jibril, peace be upon Mika'il.' The Messenger of Allah (ﷺ) said: 'Do not say this, for indeed Allah (SWT), the Mighty and Sublime, is As-Salam. Rather say: "At-tahiyyatu lillahi wasalawatu wat-tayibaat, as-salamu 'alaika ayah-Nabiyyu wa rahmatAllahi wa baraktuhu. As-salamu 'alaina a 'ala ibad illahis-salihin, ashadu an la ilaha ill Allah, wa ashhadu anna Muhammadan 'abduhu wa rasuluhu. (All compliments, prayers and pure words are due to Allah. Peace be upon you O Prophet, and the mercy of Allah and His blessings. Peace be upon us and upon the righteous slaves of Allah. I bear witness that that none has the right to be worshipped except Allah, and I bear witness that Muhammad is His slave and messenger.)"
Sunan an-Nasa'i Book 13, Hadith 99
A man came to the Prophet (ﷺ) and said, "I have been ruined for I have had sexual relation with my wife
in Ramadan (while I was fasting)" The Prophet (ﷺ) said (to him), "Manumit a slave." The man said, " I
cannot afford that." The Prophet (ﷺ) said, "(Then) fast for two successive months continuously". The man
said, "I cannot do that." The Prophet (ﷺ) said, "(Then) feed sixty poor persons." The man said, "I have
nothing (to feed them with)." Then a big basket full of dates was brought to the Prophet. The Prophet (ﷺ)
said, "Where is the questioner? Go and give this in charity." The man said, "(Shall I give this in
charity) to a poorer person than l? By Allah, there is no family in between these two mountains (of
Medina) who are poorer than we." The Prophet (ﷺ) then smiled till his premolar teeth became visible, and
said, "Then (feed) your (family with it).
Sahih al-Bukhari Book 78, Hadith 115
The Prophet (ﷺ) said, "A man used to do sinful deeds, and when death came to him, he said to his sons,
'After my death, burn me and then crush me, and scatter the powder in the air, for by Allah, if Allah
has control over me, He will give me such a punishment as He has never given to anyone else.' When
he died, his sons did accordingly. Allah ordered the earth saying, 'Collect what you hold of his
particles.' It did so, and behold! There he was (the man) standing. Allah asked (him), 'What made you
do what you did?' He replied, 'O my Lord! I was afraid of You.' So Allah forgave him. " Another
narrator said "The man said, Fear of You, O Lord!"
Sahih al-Bukhari Book 60, Hadith 148
I was asked about the invokers of curses during the reign of Mus'ab (b. Zubair) whether they could separate (themselves by this process). He said: I did not understand what to say. So I went to the house of Ibn 'Umar (Allah be pleased with them) in Mecca. I said to his servant: Seek permission for Me. He said that he (Ibn 'Umar) had been taking rest. He (Ibn 'Umar) heard my voice. and said: Are you Ibn Jubair? I said: Yes. He'said: Come in. By Allah, it must be some (great) need which has brought you here at this Hour. So I got in and found him lying on a blanket reclining against a pillow stuffed with fibres of date-palm. I said: O Abu'Abd al-Rahman, should there be separation between the invokers of curses? He said: Hallowed be Allah, yes, The first one who asked about it was so and so. he said: Messenger of Allah, tell me If one of us finds his wife committing adultery: what should he do? If he talks, that is something great, and if he keeps quiet that is also (something great) (which he cannot afford to do). Allah's Prophet (ﷺ) kept quiet (or some time). After some time he (that very person) came to him (Allah's Messenger) and said: I have been involved in that very cage about which I had asked you Allah the Exalted and Majestic then revealed (these) verses of Surah Nur:" Those who accuse their wives" (verse 6), and he (the Holy Prophet) recited them to him and admonished him, and exhorted him and informed him that the torment of the world is less painful than the torment of the Hereafter. He said: No, by Him Who sent you with Truth, I did not tell a lie against her. He (the Holy Prophet) then called her (the wife of that person who had accused her) and admonished her, and exhorted her, and informed her that the torment of this world is less painful than the torment of the Hereafter. She said: No, by Him Who sent thee with Truth, he is a liar. (it was) the man who started the swearing of oath and he swore in the name of Allah four times that he was among the truthful. and at the fifth turn he said: Let there be curse of Allah upon him if he were among the liars. Then the woman was called and she swore four times in the name of Allah that he (her husband) was among the liars, and at the fifth time (she said): Let there be curse upon her if he were among the truthful. He (the Holy Prophet) then effected separation between the two.
