Al-Adab Al-Mufrad, Book 30, Hadith 575 (English) ⓘ

Ibn 'Abbas said, "I never cease to wonder at dogs and sheep. Such-and-such a number of sheep were slaughtered in the year and such-and-such a number were sacrificed for hajj. One bitch has a litter of such-and-such a number of puppies, and sheep have more than the dog."

حَدَّثَنَا عَمْرُو بْنُ مَرْزُوقٍ، قَالَ‏:‏ أَخْبَرَنَا شُعْبَةُ، عَنْ عُمَارَةَ بْنِ أَبِي حَفْصَةَ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ قَالَ‏:‏ عَجِبْتُ لِلْكِلاَبِ وَالشَّاءِ، إِنَّ الشَّاءَ يُذْبَحُ مِنْهَا فِي السَّنَةِ كَذَا وَكَذَا، وَيُهْدَى كَذَا وَكَذَا، وَالْكَلْبُ تَضَعُ الْكَلْبَةُ الْوَاحِدَةُ كَذَا وَكَذَا وَالشَّاءُ أَكْثَرُ مِنْهَا‏.‏
