Sahih al-Bukhari 1668

Arabic

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جُوَيْرِيَةُ، عَنْ نَافِعٍ، قَالَ كَانَ عَبْدُ اللَّهِ بْنُ عُمَرَ ـ رضى الله عنهما ـ يَجْمَعُ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ بِجَمْعٍ، غَيْرَ أَنَّهُ يَمُرُّ بِالشِّعْبِ الَّذِي أَخَذَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَيَدْخُلُ فَيَنْتَفِضُ وَيَتَوَضَّأُ، وَلاَ يُصَلِّي حَتَّى يُصَلِّيَ بِجَمْعٍ‏.‏

Translation

Narrated Nafi`:`Abdullah bin `Umar used to offer the Maghrib and `Isha' prayers together at Jam' (Al-Muzdalifa). But he used to pass by that mountain pass where Allah's Messenger (ﷺ) went, and he would enter it and answer the call of nature and perform ablution, and would not offer any prayer till he had prayed at Jam
