1- الإمامُ الصّادقُ عليه السلام لأبي العبّاسِ في المُباهَله : تُشَبِّكُ أصابِعَكَ في أصابِعِهِ ثُمَّ تقولُ: «اللّهُمَّ إنْ كانَ فُلانٌ جَحَدَ حقّا وأقَرَّ بباطلٍ فأصِبْهُ بِحُسْبانٍ مِن السَّماءِ أو بِعذابٍ مِن عِندِكَ» وتُلاعِنُهُ سَبعينَ مرّةً.
1. Imam al-Sadiq (AS) said to AbU al-‘AbbÁs about the reciprocal invocation of Allah’s curse, ‘You cross your fingers with his fingers and say, ‘O Allah! If so-and-so has disputed the truth and attested to a falsehood, then strike him with a bolt from the sky or some torment from You.’ Then you exchange curses with him seventy times.’
2- الإمامُ الصّادقُ عليه السلام: إنّ نَصارى نَجْرانَ لَمّا وَفَدوا على رسولِ اللّه صلى الله عليه و آله وكانَ سيّدُهُم الأهْتَمَ والعاقِبَ والسَّيّدَ ... فقالوا: إلى ما تَدْعونا ؟ فقالَ: إلى شَهادَةِ أنْ لا إلهَ إلاّ اللّه وأنّي رسولُ اللّه وأنّ عيسى عَبدٌ مَخلوقٌ يأكُلُ ويَشْرَبُ ويُحْدِثُ ... فقالَ رسولُ اللّه صلى الله عليه و آله: فباهِلُوني، فإنْ كُنتُ صادقا اُنزِلَتِ اللّعنةُ علَيكُم، وإنْ كنتُ كاذبا اُنزِلَتْ علَيَّ، فقالوا: أنْصَفْتَ، فتَواعَدوا للمُباهَلةِ. فلَمّا رجَعوا إلى مَنازِلهم قالَ رؤساؤهُم ...: إنْ باهَلَنا بقَومِهِ باهَلْناهُ، فإنَّهُ ليسَ بِنَبيٍّ، وإنْ باهَلَنا بأهْلِ بَيتِهِ خاصّةً فلا نُباهِلُهُ، فإنَّهُ لا يُقْدِمُ على أهلِ بيتِهِ إلاّ وهُو صادقٌ. فلَمّا أصبَحوا جاؤُوا إلى رسولِ اللّه صلى الله عليه و آله ومعَهُ أميرُ المؤمنينَ وفاطمةُ والحسنُ والحسينُ ... فَفَرِقوا وقالوا لرسولِ اللّه صلى الله عليه و آله: نُعْطيكَ الرِّضا فَأعْفِنا عنِ المُباهَله، فصالَحَهُم رسولُ اللّه صلى الله عليه و آله على الجِزيةِ وانْصَرَفُوا.
2. Imam al-Sadiq (AS) said, ‘When the Christians of Najran came to the Prophet (SAWA), their chiefs were al-Ahtam, al-ÝÀqib and al-Sayyid…they asked, ‘To what do you call us?’ He said, ‘To bear witness that there is no god but Allah and that I am the Messenger of Allah, and that Jesus was a created servant who ate, drank
[water] and relieved himself’… the Prophet (SAWA) said, ‘Then invoke Allah’s curse upon me. If I am telling the truth, the curse will descend upon yourselves and if not, then it will descend upon me.’ They said, ‘You have spoken fairly.’ Then they made an appointment for the challenge. When they returned to their homes, their chiefs told them…‘If he comes to invoke curse upon us with his people, we will accept the challenge, because he would not be a prophet, but if he challenges us with his close family, we must not accept, for he would not risk his own family unless he was truthful. When the morning arrived, they came to the Prophet (SAWA), and he was accompanied by the Commander of the Faithful, Fatima, al-Íasan, and al-Íusayn…They got scared and said to the Prophet (SAWA), ‘We will give you what you want, so spare us this mutual invocation of curse.’ The Prophet (SAWA) made a truce with them that they pay the tax (jizya) and they went back.’
