Sacrifice - rules, guidelines and modern issues

 People living in western countries getting their animals sacrificed here

If NRIs living in the western countries are getting their animals sacrificed in India, then it is permissible if the animal is sacrificed on 10^th Dhul Hijjah, however it is better if it is done on 11^th or 12^th Dhul Hijjah, as when it is 10^th Dhul Hijjah in India, it is the night before Eid in the western countries (USA, Canada, etc.).  As per the opinion of Imam Abu Yusuf and Imam Muhammad (May Allah shower His mercy on them), the place where the sacrifice is being done will be considered and as per the opinion of Imam Hasan Bin Zyad (May Allah shower His mercy on him), the place where the person ordering the sacrifice will be considered.  As given in Fatawa A’alamgiri:

As their sacrifice is being done in India, as per the opinion of Imam Muhammad (May Allah shower His mercy on him), their sacrifice on 10th Dhul Hijjah is valid.  As per the opinion of Imam Hasan Bin Zyad (May Allah shower His mercy on him), the animal should be sacrificed when the time of sacrifice starts in the west. 

As a cautionary measure, it is better to sacrifice the animal when

the time of sacrifice has started in both the countries.
