فَمَنْ حَاجَّكَ فِيهِ مِن بَعْدِ مَا جَاءَكَ مِنَ الْعِلْمِ فَقُلْ تَعَالَوْا نَدْعُ أَبْنَاءَنَا وَأَبْنَاءَكُمْ وَنِسَاءَنَا وَنِسَاءَكُمْ وَأَنفُسَنَا وَأَنفُسَكُمْ ثُمَّ نَبْتَهِلْ فَنَجْعَل لَّعْنَتَ اللَّـهِ عَلَى الْكَاذِبِينَ

But whoever disputes with you in this matter after what has come to you of knowledge, then say: Come let us call our sons and your sons, and our women and your women, and our selves and your selves; then let us be earnest in prayer and invoke the curse of Allah upon the liars. (Qur’an 3:61).

This event is one of the reasosn used by Imam Ali (a.s) to prove for people his rights:

‘Ali argued with the committee members saying: "I adjure you in the name of Allah, is there anyone amongst you closer in relationship to the Messenger of Allah than me? Is there any other man whom the Prophet made him ‘his (own) soul’ (Nafs), and that he made his children ‘his (own) children’, and his women ‘his (own) women’?”They replied: "No, by God!"
