The Islamic faith stands on five principles or pillars, written in the hadith. The first, Shahadah, states that all believers will only worship one god, Allah. The second, Salat, dictates that all Muslims will worship five times a day. At sunrise, noon, midafternoon, twilight and night facing in the direction of Mecca, Muslims will bow in prayer. The third pillar is Zakat or the giving of alms. All Muslims are expected to contribute a portion of their earnings to the helping of others: the poor, the widows, and the orphans. Fasting during the holy month of Ramadan is the fourth pillar and is known as Sawm. Ramadan is the ninth month of the Islamic calendar, and during the entire month Muslims do not eat or drink from dawn to dusk. They may eat only during the night, and at the end of the month, they celebrate with a feast with their family and friends. The fifth and final pillar of the Islamic faith is Hajj. At least once in a Muslim’s lifetime, they are to visit the city of Mecca and pay respect to the Kaaba. Based on the information in the passage, Islamic pillars state:

a
People of Islamic faith must always pray in the temple
b
Praying to saints and idols is encouraged
c
Prayer should include songs of praise
d
People should believe in one single god
