Musnad Ahmad 25:1239

'Abd al-Samad narrated to us, 'Abd Rabbih ibn Bariq al-Hanafi narrated to us, Simak Abu Zumayl al-Hanafi narrated to us, he said: I heard Ibn 'Abbas saying: I heard the Messenger of Allah, peace and blessings of Allah be upon him, saying: "Whoever among my nation has two who preceded him [in death], will enter Paradise." 'Aisha said: May my father be sacrificed for you, what about one who has one who preceded him? He said: "And whoever has one who preceded him, O successful one." She said: What about one from your nation who has no one who preceded him? He said: "Then I am the one who precedes my nation; they will not be afflicted with the likes of me."
