I heard the Messenger of Allah (ﷺ) saying (the version of Sulayman has: The Messenger of Allah (ﷺ) used to say) after his prayer:-
"O Allah, our Lord and Lord of everything, I bear witness that Thou art the Lord alone Who hast no partner; O Allah, Our Lord and Lord of everything, I bear witness that Muhammad is Thy servant and Thy apostle ; O Allah, our Lord and Lord of everything, I bear witness that all the servants are brethren; O Allah, our Lord and Lord of everything make me sincere to Thee, and my family too at every moment, in this world and in the world hereafter, O Possessor of glory and honour, listen to me and answer. Allah is incomparably great. O Allah, Light of the heavens and of the earth".
The narrator Sulaiman b. Dawud said: "Lord of the heavens and of the earth, Allah is incomparably great. Allah is sufficient for me; and the excellent guardian is He; Allah is incomparably great.
Sunan Abi Dawud Book 8, Hadith 93
“The Messenger of Allah (ﷺ) slept near me one day,
then he woke up smiling. I said: ‘O Messenger of Allah, what has
made
you smile?’ He said: ‘People of my nation who were shown to
me (in my
dream) riding across this sea like kings on thrones.’ I
said:
‘Supplicate to Allah to make me one of them.’” So he
prayed for her.
Then he slept again, and did likewise, and she said
the same as she
said before, and he replied in the same manner. She
said: “Pray to
Allah to make me one of them,” and he said: “You
will be one of the
first ones.” He said: “Then she went out with
her husband, ‘Ubadah bin
Samit, as a fighter, the first time that
the Muslims crossed the sea
with Mu’awiyah bin Abu Sufyan. On their
way back, after they had
finished fighting, they stopped in Sham. An
animal was brought near
for her to ride it, but it threw her off, and
she died.”
Sunan Ibn Majah Book 24, Hadith 24
From Ma`mar as below.
Narrated Abu Huraira:
The Prophet (ﷺ) said, "I met Moses on the night of my Ascension to heaven." The Prophet (ﷺ) then described
him saying, as I think, "He was a tall person with lank hair as if he belonged to the people of the tribe
of Shanu's.' The Prophet (ﷺ) further said, "I met Jesus." The Prophet (ﷺ) described him saying, "He was one
of moderate height and was red-faced as if he had just come out of a bathroom. I saw Abraham whom
I resembled more than any of his children did." The Prophet (ﷺ) further said, "(That night) I was given
two cups; one full of milk and the other full of wine. I was asked to take either of them which I liked,
and I took the milk and drank it. On that it was said to me, 'You have taken the right path (religion). If
you had taken the wine, your (Muslim) nation would have gone astray."
Sahih al-Bukhari Book 60, Hadith 108
the Prophet came to visit 'Abdullah bin Thabit (when he was sick) and found him very close to death. He called out to him and he did not respond, so the Messenger of Allah said: "Truly, to Allah we belong and truly, to Him we shall return," and said: "We wanted you to live but we were overtaken by the decree of Allah, O Abu Ar-Rabi." The women screamed and wept, and Ibn "Atik started telling them to quiet. The Messenger of Allah said: "Leave them; when the inevitable comes, no one should weep." They said: "What is the inevitable, O Messenger of Allah?" He said: "Death." His daughter said: "I had hoped that you would become a martyr, for you had prepared yourself for it." The Messenger of Allah said: "Allah, the Mighty and Sublime, has rewarded him according to his intention. What do you think martyrdom is?" They said: "Being killed for the sake of Allah." The Messenger of Allah said: "Martyrdom is of seven types besides being killed for the sake of Allah. The one who dies of the plague is a martyr; the one who is crushed by a falling building is a martyr; the one who is crusheds by a falling building is a martyr; the one who dies of pleurisy is a martyr; the one who dies of pleurisy is a martyr; the one who is burned to death is a martyr, and the woman who dies in pregnancy is a martyr."
