"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."
a man came to the Prophet accompanied by a son of his. He said to him: "Do you love him?" He said: "May Allah love you as I love him." Then he (the son) died and he noticed his absence and asked about him. He said: "Will it not make you happy to know that you will not come to any of the gates of Paradise but you will find him there, trying to open it for you?"
'Amr bin Shu'aib wrote to 'Abdullah bin 'Abdur-Rahman bin Abi Husain to offer condolences for a son of his who had died. In his letter he mentioned that he had heard his father narrate, that his grandfather, 'Abdullah bin 'Amr bin Al-As said: "The Messenger of Allah said: 'Allah does not approve for His believing slave, if He takes away his loved one from among the people of the Earth, and he bears that with patience and seeks reward, and says that which he is commanded any reward less than Paradise."'
"Whoever seeks reward for (the loss of) three of his own children, he will enter Paradise." A woman stood up and said: "Or two?" He said: "Or two." The woman said: "I wish that I had said, 'or one."'
"The Messenger of Allah said: 'There is no Muslim, three of whose children die before reaching puberty, but Allah will admit him to Paradise by virtue of His mercy towards them."'
"I met Abu Dharr and said: 'Tell me a Hadith.' He said: the Messenger of Allah said: There are no two Muslims, three of whose children die before reaching puberty, but Allah will forgive them by virtue of His mercy towards them."'
"There are no two Muslims, three of whose children die before reaching puberty, but Allah will admit them to Paradise by virtue of His mercy toward them. It will be said to them: 'Enter Paradise.' They will say: 'Not until our parents enter.' So it will be said: 'Enter Paradise, you and your parents."'
"A woman came to the Messenger of Allah with a son of hers who was ill and said: 'O Messenger of Allah, I fear for him, and I have already lost three.' The Messenger of Allah said: "You have a great protection against the Hellfire."
