Al-Adab al-Mufrad 575
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.
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."
