It was narrated that ‘Amir said:“Iyad Al-Ash’ari was in Anbar at the time of ‘Eid, and he said: ‘Why is it that I do not see you engaged in Taqlis* as was done in the presence of the Messenger of Allah (ﷺ)?’”*Taqlis means to indulge in celebrations on a festive occasion.
حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنَا شَرِيكٌ، عَنْ مُغِيرَةَ، عَنْ عَامِرٍ، قَالَ شَهِدَ عِيَاضٌ الأَشْعَرِيُّ عِيدًا بِالأَنْبَارِ فَقَالَ مَالِي لاَ أَرَاكُمْ تُقَلِّسُونَ كَمَا كَانَ يُقَلَّسُ عِنْدَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ .
