I was sitting with the Messenger of Allah (ﷺ) and a man was offering prayer. He then made supplication: O Allah, I ask Thee by virtue of the fact that praise is due to Thee, there is no deity but Thou, Who showest favour and beneficence, the Originator of the Heavens and the earth, O Lord of Majesty and Splendour, O Living One, O Eternal One.
The Prophet (ﷺ) then said: He has supplicated Allah using His Greatest Name, when supplicated by this name, He answers, and when asked by this name He gives.
Sunan Abi Dawud Book 8, Hadith 80
When the ditch was dug, I saw Allah's Messenger (may peace he upon him) feeling very hungry. I came to my wife and said to her: Is there anything with you? I have seen Allah's Messenger (ﷺ) feeling extremely hungry. She brought out a bag of provisions which contained a sa', of barley. We had also with us a lamb. I slaughtered it. She ground the flour. She finished (this work) along with me. I cut it into pieces and put it in the earthen pot and then returned to Allah's Apostle (ﷺ) (for inviting him). She said: Do not humiliate me in the presence of Allah's Messenger (ﷺ) and those who are with him. When I came to him I whispered to him saying: Allah's Messenger, we have slaughtered a lamb for you and she has ground a sa' of barley which we had with us. So you come along with a group of people with you. Thereupon Allah's Messenger (ﷺ) said loudly: O people of the ditch, Jabir has arranged a feast for you, so (come along). Allah's Messenger (ﷺ) said: Do not remove your earthen pot from the hearth and do not bake the bread from the kneaded flour until I come. So I came and Allah's Messenger (ﷺ) came and he was ahead of the people; and I came to my wife and she said (to me): You will be humbled. I said: I did what you had asked me to do. She (his wife) said: I brought out the kneaded flour and Allah's Messenger (ﷺ) put some saliva of his in that and blessed It. He then put saliva in the earthen pot and blessed it and then said. Call another baker who can bake with you. and bring out the soup from it, but do not remove it from the hearth, and the guests were one thousand. (Jabir said): I take an oath by Allah that all of them ate (the food to their fill) until they left it and went away and our earthen pot was brimming over as before, and so was the case with our flour, or as Dahhak (another narrator) said: It (the flour) was in the same condition and loaves had been prepared from that.
Sahih Muslim Book 36, Hadith 189
The Prophet (ﷺ) said, "I saw myself (in a dream) entering Paradise, and behold! I saw Ar-Rumaisa', Abu
Talha's wife. I heard footsteps. I asked, Who is it? Somebody said, 'It is Bilal ' Then I saw a palace
and a lady sitting in its courtyard. I asked, 'For whom is this palace?' Somebody replied, 'It is for
`Umar.' I intended to enter it and see it, but I thought of your (`Umar's) Ghira (and gave up the
attempt)." `Umar said, "Let my parents be sacrificed for you, O Allah's Messenger (ﷺ)! How dare I think of
my Ghira (self-respect) being offended by you?
