Open it for him and give him glad tidings of Paradise and, lo, it was Abu Bakr. I opened (the gate) for him and gave him the glad tidings of Paradise. Then another person asked for the door to be opened, whereupon he said: Open it and give him the glad tidings of Piradise. He said: I went away and, lo, it was 'Umar. I opened it for him and gave him the glad tidings of Paradise. Then still another man asked for the door to be opened, and thereupon Allah's Apostle (ﷺ) said: Open it and give him the glad tidings of Paradise after a trial would afflict him. I went and, lo, it was 'Uthman b. 'Affan. 1 opened the door and gave him the glad tidings of Paradise and informed him (what the Prophet had said). Thereupon he said: O Allah, grant me steadfastness. Allah is one Whose help is to be sought.
Sahih Muslim Book 44, Hadith 42
While we were sitting in the company of the Prophet (ﷺ) a woman came to him and presented herself (for
marriage) to him. The Prophet (ﷺ) looked at her, lowering his eyes and raising them, but did not give a
reply. One of his companions said, "Marry her to me O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) asked (him),
"Have you got anything?" He said, "I have got nothing." The Prophet (ﷺ) said, "Not even an iron ring?"
He Sa`d, "Not even an iron ring, but I will tear my garment into two halves and give her one half and
keep the other half." The Prophet; said, "No. Do you know some of the Quran (by heart)?" He said,
"Yes." The Prophet (ﷺ) said, "Go, I have agreed to marry her to you with what you know of the Quran (as
her Mahr)."
Sahih al-Bukhari Book 67, Hadith 68
"Usamah bin Zaid told me: 'The daughter of the Prophet sent word to him telling him: A son of mine is dying, come to us. He sent word to her, conveying his greeting of salam and saying: "To Allah belongs that which He takes and that which He gives, and everything has an appointed time with Allah. Let her be patient and seek reward." She sent word to him adjuring him to go to her. So he got up and went, accompanied by Sa'd bin 'Ubadah, Muadh bin Jabal, Ubayy bin Kab Zaid bin Thabit and some other men. The boy was lifted up to the Messenger of Allah, with the death rattle sounding in him, and his eyes filled with tears. Sa'd said: "O Messenger of Allah, what is this?" he said: "This is compassion which Allah has created in the hearts of His slaves. Allah has mercy on His compassionate slaves."
