It is narrated from Sayyiduna Abdullah Muzani رضي الله عنه that the Messenger of Allah صلى الله عليه وسلم said: "Do not let the Bedouins ever prevail over you regarding the name of Maghrib prayer." He says, the Bedouins call it 'Isha. Imam Abu Bakr رحمه الله says that Abdullah Muzani is Abdullah bin Mughaffal رضي الله عنه.
