* Followers of the Maliki Madhab say this line twice instead of four times.

** The line "I bear witness that Ali is the vice regent of God" is recited by Shias, but NOT as a part of the Adhan. Rather, according to Shia scholars it is preferable with the intention of Qurbat. A phrase like "Ameer-ul-Mu'mineen" (The Commander of the Faithful), may be added to the end of that line. Sometimes a variation of it may be recited the second time (such as "ash'hadu anna aliyyan amir al-mo'mineena wali'ul-lah" - I bear witness that Ali, The Commander of the Faithful is the Friend of Allah).

*** The line "Prayer is better than sleep" is recited by Sunnis only for the first prayer of the day at dawn (fajr salat).

**** Shias repeat this line twice.
