Quran: Let us gather our sons and your sons, our women and your women, ourselves (plural) and yourselves, and let us invoke the curse of Allah on the liars.
Quran: Surah Al-Imran (3:61)
Translation: Abdul Haleem

If anyone disputes this with you now that you have been given this knowledge, say, ‘Come, let us gather our sons and your sons, our women and your women, ourselves (anfus: plural of nafs) and yourselves, and let us pray earnestly and invoke God’s rejection on those of us who are lying.

 
Translation: Qarai

Should anyone argue with you concerning him, after the knowledge that has come to you, say, ‘Come! Let us call our sons and your sons, our women and your women, our souls and your souls, then let us pray earnestly, and call down Allah’s curse upon the liars.’

 
Translation: Saheeh International

Then whoever argues with you about it after [this] knowledge has come to you - say, "Come, let us call our sons and your sons, our women and your women, ourselves and yourselves, then supplicate earnestly [together] and invoke the curse of Allah upon the liars [among us]."

‏فَمَنْ حَآجَّكَ فِيهِ مِنۢ بَعْدِ مَا جَآءَكَ مِنَ ٱلْعِلْمِ فَقُلْ تَعَالَوْا۟ نَدْعُ أَبْنَآءَنَا وَأَبْنَآءَكُمْ وَنِسَآءَنَا وَنِسَآءَكُمْ وَأَنفُسَنَا وَأَنفُسَكُمْ ثُمَّ نَبْتَهِلْ فَنَجْعَل لَّعْنَتَ ٱللَّهِ عَلَى ٱلْكَذِبِينَ
 
The Messenger of Allah (ﷺ) called 'Ali, Fatimah, Hasan and Husain and said: 'O Allah! This is my family.
Jami` at-Tirmidhi 2999
Narrated 'Amir bin Sa'd bin Abi Waqqas:

from his father who said: "When this Ayah was revealed: 'Come, let us call our sons and your sons, our women and your women... (3:61)' the Messenger of Allah (ﷺ) called 'Ali, Fatimah, Hasan and Husain and said: 'O Allah! This is my family.'"

حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا حَاتِمُ بْنُ إِسْمَاعِيلَ، عَنْ بُكَيْرِ بْنِ مِسْمَارٍ، هُوَ مَدَنِيٌّ ثِقَةٌ عَنْ عَامِرِ بْنِ سَعْدِ بْنِ أَبِي وَقَّاصٍ، عَنْ أَبِيهِ، قَالَ لَمَّا أَنْزَلَ اللَّهُ هَذِهِ الآيَةَ ‏:‏ ‏(‏ نَدْعُ أَبْنَاءَنَا وَأَبْنَاءَكُمْ ‏)‏ دَعَا رَسُولُ اللَّهِ صلى الله عليه وسلم عَلِيًّا وَفَاطِمَةَ وَحَسَنًا وَحُسَيْنًا فَقَالَ ‏"‏ اللَّهُمَّ هَؤُلاَءِ أَهْلِي ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ صَحِيحٌ ‏.
