Musnad Abu Ya'la al-Mawsili 111:140

Ubayd Allah ibn Umar narrated to us, Abd Rabbih ibn Bariq al-Hanafi narrated to us, that he heard his grandfather, Simak al-Hanafi, narrating from Ibn Abbas that the Prophet (peace and blessings of Allah be upon him) said: "O Aisha, whoever among my nation has two who have preceded him [in death] (fartayn), he will enter Paradise because of them." She said, "May my father be sacrificed for you, what about one who has one who has preceded him?" He said, "And whoever has one who has preceded him, O successful one." She said, "May my father be sacrificed for you, what about one among your nation who has no one who has preceded him?" He said, "Then I am the one who has preceded my nation; they will not be afflicted with the likes of me."
