Delaying the Tawaf of Ifadah and Sa'y, and Slaughtering the Hady at Night

Question:
In his second question, he asks: Is it permissible to delay the Tawaf of Ifadah and Sa'y until the twelfth day, and is it permissible to slaughter the hady at night? Henij Yusuf. Is it permissible to delay the Tawaf of Ifadah and Sa'y until the twelfth day, and is it permissible to slaughter the hady at night?

Answer:
Yes, you must slaughter before the Tawaf. The twelfth, the thirteenth, and the fourteenth, and the other days, and the end of the month, are all permissible, but the earlier it is, the better; the sooner it is done, the better. It is obligatory to slaughter at night or during the day. The slaughter of hady and udhiyah is done at night and during the day, meaning on the night of the eleventh, the night of the twelfth, and the night of the thirteenth, one slaughters on those nights. As for the night of the 'Id, no, one does not slaughter on that night. But the night of the eleventh, last night, and the night of the twelfth, and the night of the thirteenth, all of them are for the slaughter of hady and udhiyah.
