Musnad Ahmad 4070
Musnad of Abdullah bin Mas'ood
It was narrated that 'Abdullah said, once or twice, from The Prophet (ﷺ): “There is no judge who judges between the people but on the day of Resurrection he will be detained and an angel will take hold of the back of his head and bring him to the edge of Hell, then he will lift his head towards Allah may He be glorified and exalted, and if He says, The wrongdoer, he will throw him into Hell the depth of forty years."
