عَنْ سَعِيدِ بْنِ جُبَيْرٍ قَالَ: كُنَّا مَعَ ابْنِ عُمَرَ حَيْثُ أَفَاضَ مِنْ عَرَفَاتٍ إِلَى جَمْعٍ فَصَلَّى بِنَا الْمَغْرِبَ وَمَضَى ثُمَّ قَالَ: الصَّلَاةَ فَصَلَّى رَكْعَتَيْنِ ثُمَّ قَالَ: هَكَذَا فَعَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فِي هَذَا الْمَكَانِ كَمَا فَعَلْتُ
It is narrated from Saeed bin Jubair, he says: We were with Sayyiduna Abdullah bin Umar (may Allah be pleased with them), when he reached Muzdalifah from Arafat, he led the Maghrib prayer and without any interval immediately said, "Let us perform the (Isha) prayer," then he led two rak'ahs, and then said: "Just as I have done, the Messenger of Allah (peace and blessings be upon him) did the same at this place."
