Anas bin Malik reported,

There was a man among us from Banu Najjar who had memorized Surah al-Baqarah and Surah Al Imran, and he used to serve as a scribe for the Messenger of Allah ﷺ. He fled and went over to the People of the Book.They welcomed him warmly and said, "This man used to write for Muhammad ﷺ," and they were greatly impressed by him.It was not long before Allah broke his neck among them. They dug a grave for him and buried him, but the next morning the earth had cast him out onto its surface. They dug again and buried him, and again the earth threw him out. They dug a third time and buried him, and once more the earth cast him out. So they left him lying exposed.

Sahih

حدثنا هاشم حدثنا سليمان عن ثابت

عن أنس بن مالك قال

كان منا رجل من بني النجار قد قرأ البقرة وآل عمران وكان يكتب لرسول الله ﷺ فانطلق هاربا حتى لحق بأهل الكتاب قال فرفعوه وقالوا هذا كان يكتب لمحمد ﷺ وأعجبوا به فما لبث أن قصم الله عنقه فيهم فحفروا له فواروه فأصبحت الأرض قد نبذته على وجهها ثم عادوا فحفروا له فواروه فأصبحت الأرض قد نبذته على وجهها ثم عادوا فحفروا له فواروه فأصبحت الأرض قد نبذته على وجهها فتركوه منبوذا
