Abu Saeed Khudri reported,

We took captives on the day of Hunayn, and we used to practice withdrawal during intercourse with them, hoping to ransom them back to their families. Some of us said to one another, "Are you doing this while the Messenger of Allah ﷺ is among us? Go and ask him."So we went to him, or we mentioned this matter to him, and he said, "Not every drop of fluid produces a child. When Allah has decreed something, it will come to pass."We passed by cooking pots that were boiling, and he asked us, "What is this meat?"We replied, "The meat of donkeys."He asked, "Domestic or wild?"We answered, "Domestic."He said to us, "Then turn them over and spill them out."So we overturned them, even though we were hungry and craving the meat. And we were instructed to tie the mouths of the waterskins.

عن أبي سعيد الخدري قال

أصبنا سبايا يوم حنين، فكنا نعزل عنهن، نلتمس أن نفاديهن من أهلهن، فقال بعضنا لبعض: تفعلون هذا وفيكم رسول الله ﷺ؟ ائتوه فسلوه، فأتيناه، أو ذكرنا ذلك له، قال: ما من كل الماء يكون الولد، إذا قضى الله أمرا كان ومررنا بالقدور وهي تغلي فقال لنا: ما هذا اللحم؟ فقلنا: لحم حمر، فقال لنا: أهلية أو وحشية؟ فقلنا له: بل أهلية قال: فقال لنا: فاكفئوها، قال: فكفأناها وإنا لجياع نشتهيه قال: وكنا نؤمر أن نوكئ الأسقية.
