Musannaf Ibn Abi Shayba 33:1183

Abu Usama narrated to us, from Malik ibn Mighwal, who said: I heard Ubayd Allah ibn al-Ayzar say: Indeed, the feet on the Day of Resurrection will be like arrows in a quiver, and the fortunate one is he who finds a place for his feet to place them. And at the Scale, there is an angel calling out: "Beware, indeed so-and-so, son of so-and-so, his scales have become heavy, so he has attained a happiness after which he will never be miserable." "Beware, indeed so-and-so, son of so-and-so, his scales have become light, so he has attained a misery after which he will never be happy."
