Is it obligatory for a pilgrim to slaughter his hady in al-Haram or is it permissible to slaughter it outside al-Haram? Is it permissible to slaughter it in Malaysia and distribute the meat among the poor and the impoverished both inside and outside Malaysia?

First, it is impermissible for a pilgrim on hajj tamattu' to slaughter a hady in his country before going to Mecca for hajj. This is because the place for slaughtering is al-Haram. God the Almighty says,

Such (is his state): and whoever holds in honor the rites of God (in the sacrifice animals), such (honor) should come truly from piety of heart. In them ye have benefits for a term appointed: In the end their place of sacrifice is near the Ancient House. [Al-Hajj, 32-3]

The ruling

It is necessary for a pilgrim to slaughter his hady in Mecca. As for distributing the meat of these offerings, the principle is to distribute them among the poor of al-Haram. There is no harm in saving the meat and distributing it among them over the course of the year. If the amount of meat exceeds their needs for the current year as well as for the next, then it is permissible to distribute it among the poor in places other than al-Haram.
