Saeed bin Musayab reported,

The Bahirah was a she-camel whose milk was withheld for the idols, so no one among the people would milk her. As for the Saaibah, they used to set her free for their gods, and nothing was loaded upon her.He said, Abu Hurairah said, the Messenger of Allah ﷺ said, "I saw Amr bin Amir al-Khuzai dragging his intestines in the Fire. He was the first to set free the Sawaib."The Wasilah was the young she-camel that came first in the camel's offspring, then was followed by another female. They used to set her free for their idols if one was joined to the other without a male between them.The Ham was the male camel that performed a designated number of matings. When he had completed his matings, they would dedicate him to their idols and exempt him from carrying loads, so nothing would be loaded upon him, and they called him al-Hami.Abu al-Yaman said to me, Shuayb informed us from Zuhri, "I heard Saeed report this to him." He said, Abu Hurairah said, "I heard the Prophet ﷺ say something similar."Ibn Hadi narrated it from Ibn Shihab, from Saeed, from Abu Hurairah , "I heard the Prophet ﷺ."

حدثنا موسى بن إسماعيل حدثنا إبراهيم بن سعد عن صالح بن كيسان عن ابن شهاب

عن سعيد بن المسيب قال

البحيرة التي يمنع درها للطواغيت فلا يحلبها أحد من الناس والسائبة كانوا يسيبونها لآلهتهم لا يحمل عليها شيء قال وقال أبو هريرة قال رسول الله ﷺ رأيت عمرو بن عامر الخزاعي يجر قصبه في النار كان أول من سيب السوائب والوصيلة الناقة البكر تبكر في أول نتاج الإبل ثم تثني بعد بأنثى وكانوا يسيبونها لطواغيتهم إن وصلت إحداهما بالأخرى ليس بينهما ذكر والحام فحل الإبل يضرب الضراب المعدود فإذا قضى ضرابه ودعوه للطواغيت وأعفوه من الحمل فلم يحمل عليه شيء وسموه الحامي وقال لي أبو اليمان أخبرنا شعيب عن الزهري سمعت سعيدا قال يخبره بهذا قال وقال أبو هريرة سمعت النبي ﷺ نحوه ورواه ابن الهاد عن ابن شهاب عن سعيد عن أبي هريرة رضي الله عنه سمعت النبي ﷺ
