٤٢٨. وَقَالَ (عليه السلام) فِی بَعْضِ الْأَعْيَادِ: إِنَّمَا هُوَ عِيدٌ لِمَنْ قَبلَ اللهُ صِيَامَهُ وَشَكَرَ قِيَامَهُ، وَكُلُّ يَوْمٍ لَا يُعْصَى اللهُ فِيهِ فَهُوَ (يَوْمَ) عِيدٌ.

428. Amīr al-mu’minīn, peace be upon him, said on the occcasion of an ‘īd (Muslim feast day): It is an ‘īd for him whose fasting Allāh accepts and for whose prayers He is grateful; and (in fact) every day wherein no sin of Allāh is committed is an ‘īd. [1]
