Musa bin Salama reported,

Sinan bin Salama and I went on Hajj together, and Sinan had a sacrificial camel with him. The camel became exhausted and unable to continue, and he was at a loss as to what to do with it. So I said, "When I reach Mecca, I will inquire about this matter."When we arrived in Mecca, I said, "Let us go to Ibn Abbas." We entered upon him and he had a slave-girl with him. I had two questions and my companion had one. He said, "Shall I send her away?"I said, "No."Then I said, "I had a sacrificial camel with me, and it became exhausted on us, so I said, 'When I reach Mecca, I will inquire about this matter.'"Ibn Abbas said, "The Messenger of Allah ﷺ sent sacrificial camels with so-and-so and gave him instructions concerning them. When the man set off, he came back and said, 'Messenger of Allah, what should I do with any of them that becomes exhausted?' He said, 'Slaughter it, dip its sandal in its blood, strike the side of its body with it, and neither you nor any of your companions may eat from it.'"Then I said to him, "I take part in these military campaigns and gain spoils. I want to free a slave on behalf of my mother. Will it suffice for her if I free a slave on her behalf?"Ibn Abbas said, "The wife of Salman bin Abdullah al-Juhani instructed him to ask the Messenger of Allah ﷺ about her mother, who had died without performing Hajj. Would it suffice for her if she performed Hajj on her behalf? The Prophet ﷺ said, 'Tell me, if her mother had a debt and she paid it off on her behalf, would that suffice for her mother?' He said, 'Yes.' He said, 'Then let her perform Hajj on her mother's behalf.'"He also asked him about seawater, and he said, "The water of the sea is purifying."

عن موسى بن سلمة قال

حججت أنا وسنان بن سلمة ومع سنان بدنة فأزحفت عليه فعي بشأنها فقلت لئن قدمت مكة لأستبحثن عن هذا قال فلما قدمنا مكة قلت انطلق بنا إلى ابن عباس فدخلنا عليه وعنده جارية وكان لي حاجتان ولصاحبي حاجة فقال ألا أخليك قلت لا فقلت كانت معي بدنة فأزحفت علينا فقلت لئن قدمت مكة لأستبحثن عن هذا فقال ابن عباس بعث رسول الله ﷺ بالبدن مع فلان وأمره فيها بأمره فلما قفا رجع فقال يا رسول الله ما أصنع بما أزحف علي منها قال انحرها واصبغ نعلها في دمها واضربه على صفحتها ولا تأكل منها أنت ولا أحد من رفقتك قال فقلت له أكون في هذه المغازي فأغنم فأعتق عن أمي أفيجزئ عنها أن أعتق فقال ابن عباس أمرت امرأة سلمان بن عبد الله الجهني أن يسأل رسول الله ﷺ عن أمها توفيت ولم تحجج أيجزئ عنها أن تحج عنها فقال النبي ﷺ أرأيت لو كان على أمها دين فقضته عنها أكان يجزئ عن أمها قال نعم قال فلتحجج عن أمها وسأله عن ماء البحر فقال ماء البحر طهور
