A difference in the narrator’s name

Hadith Mu‘allal

The students transmitting this Hadith from Sufyān al-Thawrī differ as follows:

• Ya‘lā ibn ‘Ubayd: he named عمرو بن دينار (‘Amr ibn Dīnār) in the chain.
• All the other students: they named عبد الله بن دينار (‘Abd Allāh ibn Dīnār) at that place.

These are two different narrators, not two spellings of one person’s name.
