Umar II
Umar II (Umar Bin Abdul Aziz) replaced the cursing of Ali and his progeny, on the minbar during Friday prayers with verse 15 from Sura 59 (al-Hashr) and verse 90 of Sura 16 (al-Nahl) from the Qur'an. Al-Tabari mentions that the cursing of Ali definitely came to an end only with the fall of the Umayyad dynasty.
