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."

[Machine] I heard the Messenger of Allah ﷺ say, "I saw 'Amr Al-Khuza'i dragging his staff in the fire, and he was the first to introduce the practice of impaling the captives." Ibn Al-Musayyib said, "The 'Wasilah' is a female camel that gives birth to a female camel first, then it gives birth to another female camel afterwards. They used to impale it for their false deities and call it 'Al-Hamah.' When one was connected to the other, there was no male in between them." Ibn Al-Musayyib also said, "The male camel used to strike a limited number of times with his thighs. When he completed his number of strikes, he would be handed over to the false deities and they would absolve him from carrying anything. They called him 'Al-Ham'."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ رَأَيْتُ عَمْرًا الْخُزَاعِيَّ يَجُرُّ قُصْبَهُ فِي النَّارِ وَكَانَ أَوَّلَ مَنْ سَيَّبَ السَّوَائِبَ قَالَ ابْنُ الْمُسَيِّبِ وَالْوَصِيلَةُ النَّاقَةُ الْبِكْرُ تُبَكِّرُ فِي أَوَّلِ نِتَاجِ الْإِبِلِ بِالْأُنْثَى ثُمَّ تُثَنِّي بَعْدَ ذَلِكَ بِالْأُنْثَى وَكَانُوا يُسَيِّبُونَهَا لِطَوَاغِيتِهِمْ وَيَدْعُونَهَا الْوَصِيلَةَ؛ حِينَ وَصَلَتْ إِحْدَاهُمَا بِالْأُخْرَى لَيْسَ بَيْنَهُمَا ذَكَرٌ قَالَ ابْنُ الْمُسَيِّبِ وَالْحَامُ فَحْلُ الْإِبِلِ كَانَ يَضْرِبُ الضِّرَابَ الْمَعْدُودَ فَإِذَا قَضَى ضِرَابَهُ دَعَوْهُ لِلطَّوَاغِيتِ وَأَعْفَوْهُ مِنَ الْحَمْلِ فَلَمْ يَحْمِلُوا عَلَيْهِ شَيْئًا وَسَمَّوْهُ الْحَامَ
