عَنْ إِبْرَاهِيمَ بْنِ عَبْدِ اللَّهِ بْنِ فَرُّوخَ عَنْ أَبِيهِ قَالَ: صَلَّيْتُ خَلْفَ عُثْمَانَ رَضِيَ اللَّهُ عَنْهُ الْعِيدَ فَكَبَّرَ سَبْعًا وَخَمْسًا
Abdullah bin Farukh says: I offered the Eid prayer behind Sayyiduna Uthman (may Allah be pleased with him); he said seven takbeers in the first rak'ah and five takbeers in the second rak'ah.
