‘Ata` bin Farrookh · The Book of Prayer - Two Eids

As there is no Adhan on 'Id-ul-Fitr, so you should not pronounce it. Ibn Zubair did not pronounce Adhan on that day. He (Ibn 'Abbas) also sent him (with this message) that sermon (is to be delivered) after the prayer, and thus it was done. So lbn Zubair observed prayer before Khutba.
