Malik and Abu Hanifeh agree with the Shiites and say that ‘Azan’ and ‘Iqamah’ are good in all prayers whether at home or on a trip, whether said in person or in a congregation. They consider that there are no cases in which it is obligatory to say the ‘Azan’ or ‘Iqamah’. However, Ahmad ibn Hanbal as well as the Shafi`iyah and Malikiyah have said that ‘Azan and Iqamah’ are obligatory as much as necessary.

The Difference in ‘Azan’ Between the Sects The Shiites believe that there are two “Hayya Ala Khayril Amal” after “Hayya Alal Falah” but the Sunnis believe that “As Salat Khayron Min al-Nawm,” should follow in the morning prayer. Shiite scholars believe that “Haya Ala Kharil Amal” had been used during the lifetime of the Prophet , and his family and the Imams continued saying it.
