Testifying to the Wilāyah of Amir al-Mu’mineen (‘a) in Adhān (call to prayer)
Since when has the phrase for testifying to the wilāyah of Amir al-Mu’mineen Ali (‘a) been recited in the adhān (call to prayer)?
According to some traditions, this phrase has been recited as a part of the call to prayer since the age of the Infallible Imams (‘a) but it was not widely recited in that era. Later on it became the motto of the Shiʻa school (for more information, refer to the valuable book of “al-Mustamsak”, chapter on adhān and iqāmah).
