حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ أَبِي لَبِيدٍ، عَنْ أَبِي سَلَمَةَ، قَالَ سَمِعْتُ ابْنَ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ تَغْلِبَنَّكُمُ الأَعْرَابُ عَلَى اسْمِ صَلاَتِكُمْ أَلاَ وَإِنَّهَا الْعِشَاءُ وَلَكِنَّهُمْ يُعْتِمُونَ بِالإِبِلِ " .
Ibn ‘Umar reported the prophet (May peace be upon him) as saying: The desert Arabs may not dominate you in respect of the name of your prayer. Beware! It is al-`Isha, but they milk their camels when it is fairly dark. Translation Not Available
