Faith is essential in Islam. Right faith about ALLAH, the universe, and mankind is of essential concern to Muslims.
The Quran, the Holy book of Islam states:
"Righteousness is not that you turn your faces toward the east or the west, but [true] righteousness is [in] one who believes in Allah , the Last Day, the angels, the Book, and the prophets and gives wealth, in spite of love for it, to relatives, orphans, the needy, the traveler, those who ask [for help], and for freeing slaves; [and who] establishes prayer and gives zakah; [those who] fulfill their promise when they promise; and [those who] are patient in poverty and hardship and during battle. Those are the ones who have been true, and it is those who are the righteous.”
To have faith in these principles, as well as many others, are essential to the followers of Holy Prophet Muhammad (S.A.W).
Following are the five Ahadith which explains about belief or faith in Islam:
“Narrated Ibn 'Umar:
Allah's Messenger (S.A.W) said: Islam is based on (the following) five (principles):
- To testify that none has the right to be worshipped but Allah and Muhammad is Allah's Messenger (S.A.W).
- To offer the (compulsory congregational) prayers dutifully and perfectly.
- To pay Zakat (i.e. obligatory charity) .
- To perform Hajj. (i.e. Pilgrimage to Mecca)
- To observe fast during the month of Ramadan.”
“Narrated Abu Huraira:
The Prophet (S.A.W) said, "Faith (Belief) consists of more than sixty branches (i.e. parts). And Haya is a part of faith." “
Narrated 'Abdullah bin 'Amr:
The Prophet (S.A.W) said, "A Muslim is the one who avoids harming Muslims with his tongue and hands. And a Muhajir (emigrant) is the one who gives up (abandons) all what Allah has forbidden."
The Prophet (S.A.W) said, "None of you will have faith till he wishes for his (Muslim) brother what he likes for himself."
Narrated Abu Huraira:
"Allah's Messenger (S.A.W) said, "By Him in Whose Hands my life is, none of you will have faith till he loves me more than his father and his children."
