[Machine] Ali used to make takbeer (saying Allahu Akbar) after the Fajr prayer on the day of Arafah, and he would not stop until he prayed behind the imam on the last days of Tashreeq, then he would make takbeer after Asr prayer.  

كَانَ عَلِيٌّ «يُكَبِّرُ بَعْدَ صَلَاةِ الْفَجْرِ غَدَاةَ عَرَفَةَ ثُمَّ لَا يَقْطَعُ حَتَّى يُصَلِّيَ الْإِمَامُ مِنْ آخِرِ أَيَّامِ التَّشْرِيقِ ثُمَّ يُكَبِّرُ بَعْدَ الْعَصْرِ»
