ذَٰلِكَ بِأَنَّهُمُ ٱتَّبَعُوا۟ مَآ أَسْخَطَ ٱللَّهَ وَكَرِهُوا۟ رِضْوَٰنَهُۥ فَأَحْبَطَ أَعْمَٰلَهُمْ
That will be because they followed that which angereth Allah, and hated that which pleaseth Him. Therefor He hath made their actions vain.

Sahih al-Bukhari
Holding Fast to the Qur'an and Sunnah
Chapter: The religious learned men should not differ
Narrated `Abdur-Rahman bin `Abis:
Ibn `Abbas was asked, "Did you offer the Id prayer with the Prophet?" He said, "Yes, had it not been for my close relation to the Prophet, I would not have performed it (with him) because of my being too young The Prophet (ﷺ) came to the mark which is near the home of Kathir bin As-Salt and offered the Id prayer and then delivered the sermon. I do not remember if any Adhan or Iqama were pronounced for the prayer. Then the Prophet (ﷺ) ordered (the women) to give alms, and they started stretching out their hands towards their ears and throats (giving their ornaments in charity), and the Prophet (ﷺ) ordered Bilal to go to them (to collect the alms), and then Bilal returned to the Prophet.
