Bahz bin Hakim narrated from his father that his grandfather said:"I said: 'O Prophet of Allah! I did not come to you until I had sworn more that this many times' - the number of fingers on his hands - 'that I would never come to you or follow your religion. I am a man who does not know anything except that which Allah and His Messenger teach me. I ask you by the face of Allah, the Mighty and Sublime, with what has your Lord sent you to us? He said: 'With Islam.' I said: What are the signs of Islam? He said; To say: I submit my face to Allah and give up Shirk, and, to establish the Salah and to pay Zakah. Each Muslim is sacred and inviolable to his fellow Muslim; they support one another. Allah does not accept my deed from an idolater after he becomes a Muslim, until he departs from the idolaters and joins the Muslims."'
أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا الْمُعْتَمِرُ، قَالَ سَمِعْتُ بَهْزَ بْنَ حَكِيمٍ، يُحَدِّثُ عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ قُلْتُ يَا نَبِيَّ اللَّهِ مَا أَتَيْتُكَ حَتَّى حَلَفْتُ أَكْثَرَ مِنْ عَدَدِهِنَّ - لأَصَابِعِ يَدَيْهِ - أَلاَّ آتِيَكَ وَلاَ آتِيَ دِينَكَ وَإِنِّي كُنْتُ امْرَأً لاَ أَعْقِلُ شَيْئًا إِلاَّ مَا عَلَّمَنِي اللَّهُ وَرَسُولُهُ وَإِنِّي أَسْأَلُكَ بِوَجْهِ اللَّهِ عَزَّ وَجَلَّ بِمَا بَعَثَكَ رَبُّكَ إِلَيْنَا قَالَ " بِالإِسْلاَمِ " . قَالَ قُلْتُ وَمَا آيَاتُ الإِسْلاَمِ قَالَ " أَنْ تَقُولَ أَسْلَمْتُ وَجْهِيَ إِلَى اللَّهِ عَزَّ وَجَلَّ وَتَخَلَّيْتُ وَتُقِيمَ الصَّلاَةَ وَتُؤْتِيَ الزَّكَاةَ كُلُّ مُسْلِمٍ عَلَى مُسْلِمٍ مُحَرَّمٌ أَخَوَانِ نَصِيرَانِ لاَ يَقْبَلُ اللَّهُ عَزَّ وَجَلَّ مِنْ مُشْرِكٍ بَعْدَ مَا أَسْلَمَ عَمَلاً أَوْ يُفَارِقَ الْمُشْرِكِينَ إِلَى الْمُسْلِمِينَ " .
