Ibn 'Abbas (may Allah the Exalted be well pleased with him and his father) related that

he heard Allah’s Messenger say (Allah bless him and give him peace): 'If someone has two children from my Community who died an untimely death, Allah will cause him to enter the Garden of Paradise on their account,' so 'A'isha said (may Allah be well pleased with her): 'What about someone who has only one child from your Community who has died an untimely death?' He said: 'Also someone who has only one child who has died young, O favored one!' She said: 'So what about someone who does not have any child from your Community who has died as an infant?' He said: 'I am a child of my Community who died an untimely death. Never again will they be afflicted by the loss of the likes of me!'”
