What is meant by faith?
According to the complete prayer treatise book written by Ustadz Labib MZ, the definition of faith (iman) is believing with the heart, making a verbal vow, and practicing with all body parts whatever was brought by the Prophet Muhammad sallallaahu alaihi wasallam.
Faith consists of 6 pillars of faith or arkan al islam, namely faith in God, faith in God’s angels, faith in God’s books, faith in God’s messengers, faith in the Day of Judgment, and faith in good and bad destiny.
As written in the Koran, Surah An-Nisa Verse 136 :
يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوْٓا اٰمِنُوْا بِاللّٰهِ وَرَسُوْلِهٖ وَالْكِتٰبِ الَّذِيْ نَزَّلَ عَلٰى رَسُوْلِهٖ وَالْكِتٰبِ الَّذِيْٓ اَنْزَلَ مِنْ قَبْلُ ۗوَمَنْ يَّكْفُرْ بِاللّٰهِ وَمَلٰۤىِٕكَتِهٖ وَكُتُبِهٖ وَرُسُلِهٖ وَالْيَوْمِ الْاٰخِرِ فَقَدْ ضَلَّ ضَلٰلًا ۢ بَعِيْدًا (136)
Latin writing: yaa ayyuhal ladzina aamanuu aaminuu billahi wa rosulihi wal kitaabil ladzii nazzala ‘ala rosulihi wal kitaabil ladzi anzala min qoblu wa man yakfur billahi wa malaa ikatihi wa karetihi wa rusulihi wal yaumil aakhiri faqod dholla dholalan ba’idan
Meaning: O believers! Have faith in Allah, His Messenger, the Book He has revealed to His Messenger and the Scriptures He revealed before. Indeed, whoever denies Allah, His angels, His Books, His messengers, and the Last Day has gone far astray. (An Nisa verse 136)
As written in the hadith of the Prophet Sallallahu alaihi wasallam which was narrated by Muslim
الاِيْمَانُ اَنْ تُؤْمِنَ بِاللهِ وَمَلَائِكَتِهِ وَكُتُبِهِ وَرُسُلِهِ وَالْيَوْمِ اْلآخِرِ وَتُؤْمِنَ بِالْقَدْرِ خَيْرِهِ وَ شَرِّهِ مِنَ اللهِ (رواه مسلم)
Latin writing: al iimana an tu’mina billahi wa malaa ikatihi wa poleihi wa rusulihi waly aumil aakhri wa tu’mina bil qodri khoirihi wa syarrihi minallahi
meaning: Faith is that you should believe in Allah, His angels, His books, His messengers, and the Last Day, and you believe in his decision, the good and the bad from Allah SWT. (narrated by Muslim)
