It was narrated that az-Zubair said:

The Messenger of Allah (ﷺ) mentioned both of his parents together for me on the Day of ‘Uhud (i.e., in the phrase “may my father and mother be sacrificed for you`.]

حَدَّثَنَا أَبُو مُعَاوِيَةَ، حَدَّثَنَا هِشَامٌ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، عَنِ الزُّبَيْرِ، قَالَ جَمَعَ لِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَبَوَيْهِ يَوْمَ أُحُدٍ‏.‏
