Eid Salaah

Q: I read the following concerning the timing for zabihah of the qurbaani animal. Can you tell me if this is correct?

If for some reason or other Eid Salaah was not performed on Eid day (i.e. 10th Zhul-Hijjah) then it will only be ja’iz to commence sacrificing AFTER ZAWAAL on that day, i.e. after expiry of the time of Eid Salaah, which is just before zawaal. However, during the next two days, qurbani could be done at any time.

If Eid Salaah was read the following day (11th) or the day thereafter (12th) qurbaani would be ja’iz even BEFORE the Eid on these two days.

Q: With regards to Eid Salaah, in the following situations, how does a person cover up for the missed Takbeeraat:

3. If he missed the Takbeeraat of the second Rak'ah but he made it for the Rukoo'.

4. If he missed the entire second Rak'ah.
