حَدَّثَنَا عَبْدُ الْأَعْلَى حَدَّثَنَا سَعِيدٌ عَنْ مَطَرٍ عَنْ عَطَاءٍ أَنَّ ابْنَ الزُّبَيْرِ صَلَّى الْمَغْرِبَ فَسَلَّمَ فِي رَكْعَتَيْنِ وَنَهَضَ لِيَسْتَلِمَ الْحَجَرَ فَسَبَّحَ الْقَوْمُ فَقَالَ مَا شَأْنُكُمْ قَالَ فَصَلَّى مَا بَقِيَ وَسَجَدَ سَجْدَتَيْنِ قَالَ فَذُكِرَ ذَلِكَ لِابْنِ عَبَّاسٍ فَقَالَ مَا أَمَاطَ عَنْ سُنَّةِ نَبِيِّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
مسند امام احمد بن حنبل · Hadith 3285
It was narrated from 'Ata' that Ibn az-Zubair prayed Maghrib and said salam after two rak'ahs, and he got up to touch the Black Stone, and the people said Subhanallah. He said: What is the matter with you? Then he prayed the rest and did the two prostrations (of forgetfulness). That was mentioned to Ibn 'Abbas (RA) and he said: He never drifted away from the Sunnah of his Prophet (PBUH).
