Mishkat al-Masabih #586

Ibn ‘Umar reported God’s Messenger as saying, "Do not let the Bedouin take away from you the name of your prayer al-maghrib (sunset) which the Bedouin call al-'isha (evening); and do not let the Bedouin take away from you the name of your prayer al-‘isha, for it is mentioned as al-‘isha in God’s Book,1 and for they use the verb from the root ‘atama of milking camels at nightfall.” 1. (Al-Qur’an, 24:58.)
