Bahira is a she-camel whose milk is kept for the idols and nobody is allowed to milk it; Sa'iba was the she-camel which they used to set free for their gods and nothing was allowed to be carried on it. Abu Huraira said: Messenger of Allah ﷺ said, "I saw ʿAmr bin 'Amir Al-Khuzaʿi (in a dream) dragging his intestines in the Fire, and he was the first person to establish the tradition of setting free the animals (for the sake of their deities)," Wasila is the she-camel which gives birth to a she-camel as its first delivery, and then gives birth to another she-camel as its second delivery. People (in the Pre-lslamic periods of ignorance) used to let that she camel loose for their idols if it gave birth to two she-camels successively without giving birth to a male camel in between. 'Ham' was the male camel which was used for copulation. When it had finished the number of copulations assigned for it, they would let it loose for their idols and excuse it from burdens so that nothing would be carried on it, and they called it the 'Hami.' Abu Huraira said, "I heard the Prophet ﷺ saying so."  

الْبَحِيرَةُ الَّتِي يُمْنَعُ دَرُّهَا لِلطَّوَاغِيتِ فَلاَ يَحْلُبُهَا أَحَدٌ مِنَ النَّاسِ وَالسَّائِبَةُ كَانُوا يُسَيِّبُونَهَا لآلِهَتِهِمْ لاَ يُحْمَلُ عَلَيْهَا شَىْءٌ قَالَ وَقَالَ أَبُو هُرَيْرَةَ قَالَ رَسُولُ اللَّهِ ﷺ رَأَيْتُ عَمْرَو بْنَ عَامِرٍ الْخُزَاعِيَّ يَجُرُّ قُصْبَهُ فِي النَّارِ كَانَ أَوَّلَ مَنْ سَيَّبَ السَّوَائِبَ وَالْوَصِيلَةُ النَّاقَةُ الْبِكْرُ تُبَكِّرُ فِي أَوَّلِ نِتَاجِ الإِبِلِ ثُمَّ تُثَنِّي بَعْدُ بِأُنْثَى وَكَانُوا يُسَيِّبُونَهُمْ لِطَوَاغِيتِهِمْ إِنْ وَصَلَتْ إِحْدَاهُمَا بِالأُخْرَى لَيْسَ بَيْنَهُمَا ذَكَرٌ وَالْحَامِ فَحْلُ الإِبِلِ يَضْرِبُ الضِّرَابَ الْمَعْدُودَ فَإِذَا قَضَى ضِرَابَهُ وَدَعُوهُ لِلطَّوَاغِيتِ وَأَعْفَوْهُ مِنَ الْحَمْلِ فَلَمْ يُحْمَلْ عَلَيْهِ شَىْءٌ وَسَمَّوْهُ الْحَامِيَ وَقَالَ لي أَبُو الْيَمَانِ أَخْبَرَنَا شُعَيْبٌ عَنِ الزُّهْرِيِّ سَمِعْتُ سَعِيدًا قَالَ يُخْبِرُهُ بِهَذَا قَالَ وَقَالَ أَبُو هُرَيْرَةَ سَمِعْتُ النَّبِيَّ ﷺ نَحْوَهُ وَرَوَاهُ ابْنُ الْهَادِ عَنِ ابْنِ شِهَابٍ عَنْ سَعِيدٍ عَنْ أَبِي هُرَيْرَةَ ؓ سَمِعْتُ النَّبِيَّ ﷺ  

[Machine] I heard the Messenger of Allah ﷺ saying: "I saw Amr bin Amir Al-Khuza'i dragging his staff in the fire. He was the first to introduce something harmful. Sa'id said: "The harmful thing that is liable to harm does not carry anything on it." And the lake whose water the transgressors are prohibited from drawing, no one milks it. And the young she-camel that is the first to bring forth after the she-camel gives birth to a female, then it gives birth to another female, they used to cast it for the transgressors. They used to call it "Al-Wasilah" if one of them was connected with the other. And the stallion, the male of the camels, strikes ten times as much as the female camels. When he finishes his covering, they let him loose for the transgressors and he is exempted from carrying anything. So they called him "Al-Ham" and they mentioned it in the Sahih from the Hadith of Salih bin Kaysan and others, from Ibn Shihab. Al-Bukhari said: "And Ibn Al-Had."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ رَأَيْتُ عَمْرَو بْنَ عَامِرٍ الْخُزَاعِيَّ يَجُرُّ قُصْبَهُ فِي النَّارِ كَانَ أَوَّلَ مَنْ سَيَّبَ السَّوَائِبَ قَالَ سَعِيدٌ السَّائِبَةُ الَّتِي تُسَيَّبُ فَلَا يُحْمَلُ عَلَيْهَا شَيْءٌ وَالْبَحِيرَةُ الَّتِي يُمْنَعُ دَرُّهَا لِلطَّوَاغِيتِ فَلَا يَحْلِبُهَا أَحَدٌ وَالْوَصِيلَةُ النَّاقَةُ الْبِكْرُ تُبَكِّرُ فِي أَوَّلِ نِتَاجِ الْإِبِلِ بِأُنْثَى ثُمَّ تُثَنِّي بَعْدُ بِأُنْثَى فَكَانُوا يُسَيِّبُونَهَا لِلطَّوَاغِيتِ يَدْعُونَهَا الْوَصِيلَةَ إِنْ وَصَلَتْ إِحْدَاهُمَا بِالْأُخْرَى وَالْحَامُ فَحْلُ الْإِبِلِ يَضْرِبُ الْعَشْرَ مِنَ الْإِبِلِ فَإِذَا قَضَى ضِرَابَهُ جَدَعُوهُ لِلطَّوَاغِيتِ فَأَعْفَوْهُ مِنَ الْحَمْلِ فَلَمْ يَحْمِلُوا عَلَيْهِ شَيْئًا فَسَمَّوْهُ الْحَامَ أَخْرَجَاهُ فِي الصَّحِيحِ مِنْ حَدِيثِ صَالِحِ بْنِ كَيْسَانَ وَغَيْرِهِ عَنِ ابْنِ شِهَابٍ قَالَ الْبُخَارِيُّ وَرَوَاهُ ابْنُ الْهَادِ
