It was narrated from Nu’man bin Bashir that the Messenger of Allah ﷺ used to recite "Glorify the Name of your Lord, the Most High," Al-A’la (87) and "Has there come to you the narration of the overwhelming?" Al-Ghashiyah (88) in the 'Eid prayer.
This hadith also teaches us that we should always be mindful of our faith in Allah and strive to remember Him in all aspects of our lives - even on special occasions like 'Eid. We should take time out from our celebrations to remember Him and thank Him for all that He has given us. It is a reminder that no matter how much we celebrate or how happy we may be on these days, it is important not to forget about God's blessings upon us.
