I read in some books of fiqh that it is mustahabb for the person who is doing ‘Umrah to sacrifice a hadiy after his ‘umrah. Is this one of the Sunnahs that have been forgotten in our time?.
This is one of the Sunnahs that have been forgotten in our time, but it is not Sunnah if you have done ‘Umrah to buy a sheep and slaughter it; the Sunnah is to bring a sheep with you from your country or at least from the miqaat or the closest point outside the sanctuary, according to some scholars, and this is called driving the hadiy. But offering a sacrifice after ‘Umrah without having brought the animal with you is not part of the Sunnah. End quote.
