Q. Can I offer (optional) Salaah at the place where Eid Salaah will take place BEFORE Eid Salaah? 

Iftikhar Ahmed,

(WORCESTER) 

A. It is Makruh to offer any other prayer on that day at the place where Eid prayer is offered - neither before the prayer nor after it. However, it is not Makruh to offer any prayer after the Eid prayer at home. But, to do so even at home before the Eid prayer is also Makruh. 

(VERILY, ALLAH TAA’LA IS ALL-KNOWING!)
