Suhayb reported,

The Messenger of Allah ﷺ related, in the story of the boy of the People of the Trench, that the king handed him over to a group of his men and said, "Take him to such-and-such a mountain. Climb the mountain with him, and when you reach its summit, if he renounces his religion, let him be. Otherwise, throw him down."So they took him and climbed the mountain with him. The boy said, "O Allah, deal with them however You will."The mountain shook beneath them, and they fell off… and the hadith continues.

عن صهيب

أن رسول الله ﷺ قال في قصة غلام أصحاب الأخدود: أن الملك دفعه إلى نفر من أصحابه، فقال: اذهبوا به إلى جبل كذا وكذا، فاصعدوا به الجبل، فإذا بلغتم ذروته، فإن رجع عن دينه، وإلا فاطرحوه، فذهبوا به فصعدوا به الجبل، فقال: اللهم اكفنيهم بما شئت، فرجف بهم الجبل فسقطوا… الحديث.
