Book 10: Call to Prayers (Adhaan) · Narrated by `Abdullah
Arabic
حَدَّثَنَا أَبُو الْوَلِيدِ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ سُلَيْمَانَ، عَنْ عُمَارَةَ بْنِ عُمَيْرٍ، عَنِ الأَسْوَدِ، قَالَ قَالَ عَبْدُ اللَّهِ لاَ يَجْعَلْ أَحَدُكُمْ لِلشَّيْطَانِ شَيْئًا مِنْ صَلاَتِهِ، يَرَى أَنَّ حَقًّا عَلَيْهِ أَنْ لاَ يَنْصَرِفَ إِلاَّ عَنْ يَمِينِهِ، لَقَدْ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم كَثِيرًا يَنْصَرِفُ عَنْ يَسَارِهِ.
English translation
Narrated `Abdullah:You should not give away a part of your prayer to Satan by thinking that it is necessary to depart (after finishing the prayer) from one's right side only; I have seen the Prophet (ﷺ) often leave from the left side
