Abu Hurairah reported,

Maez bin Malik came to the Prophet ﷺ and said, "I have committed adultery."The Prophet ﷺ turned away from him.Then he said again, "I have committed adultery."The Prophet ﷺ turned away from him.Then he said, "I have committed adultery."The Prophet ﷺ turned away from him.Then he said, "I have committed adultery."The Prophet ﷺ turned away from him, until he had said it four times. So the Prophet ﷺ ordered that he be stoned. When the stones struck him, he turned and fled, running. A man met him carrying the jawbone of a camel and struck him with it, knocking him down. The Prophet ﷺ was told of how he fled when the stones hit him, and he said, "Why did you not let him go?"

عن أبي هريرة قال

جاء ماعز بن مالك إلى النبي ﷺ فقال: إني زنيت. فأعرض عنه. ثم قال: إني زنيت، فأعرض عنه، ثم قال: إني زنيت، فأعرض عنه، ثم قال: إني زنيت، فأعرض عنه حتى قال أربع مرات. فأمر به أن يرجم فلما أصابته الحجارة أدبر يشتد، فلقيه رجل بيده لحي جمل، فضربه فصرعه فذكر للنبي ﷺ فراره حين مسته الحجارة فقال: فهلا تركتموه؟
