Musnad Ahmad 529:2

Isma'il ibn 'Umar and Hasan ibn Musa narrated to us, they said: Hariz narrated to us, from Shurahbil ibn Shuf'ah al-Rahbi, who said: I heard 'Utbah ibn 'Abd al-Sulami, a companion of the Prophet, may Allah bless him and grant him peace, that he heard the Prophet, may Allah bless him and grant him peace, say: "Whoever dies—and Hasan said: I heard the Messenger of Allah, may Allah bless him and grant him peace, say: There is no Muslim man who passes away—having three children who have not reached the age of puberty, except that they will meet him at the eight gates of Paradise; he shall enter through whichever of them he wishes."
