The foundational hadith
بُنِيَ الْإِسْلَامُ عَلَى خَمْسٍ: شَهَادَةِ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ، وَإِقَامِ الصَّلَاةِ، وَإِيتَاءِ الزَّكَاةِ، وَالْحَجِّ، وَصَوْمِ رَمَضَانَIslam is built upon five: testifying that there is no god but God and that Muhammad is the Messenger of God, establishing prayer, paying zakat, performing Hajj, and fasting Ramadan.
1. The Shahada
The key to entering Islam: “I bear witness that there is no god but God and that Muhammad is the Messenger of God.” It means worshipping God alone and accepting the Prophet’s ﷺ message.
2. Prayer (Salah)
Five prayers each day and night, a direct link between the servant and his Lord.
فَإِذَا قَضَيۡتُمُ ٱلصَّلَوٰةَ فَٱذۡكُرُواْ ٱللَّهَ قِيَٰمٗا وَقُعُودٗا وَعَلَىٰ جُنُوبِكُمۡۚ فَإِذَا ٱطۡمَأۡنَنتُمۡ فَأَقِيمُواْ ٱلصَّلَوٰةَۚ إِنَّ ٱلصَّلَوٰةَ كَانَتۡ عَلَى ٱلۡمُؤۡمِنِينَ كِتَٰبٗا مَّوۡقُوتٗا当你们完成拜功的时候，你们当站着、坐着、躺着记念安拉。当你们安宁的时候，你们当谨守拜功。拜功对于信士，确是定时的义务。
3. Zakat
An obligatory charity from those who are able, a set share of savings above a minimum threshold (2.5% of qualifying wealth held for a lunar year) given to the poor and needy, purifying wealth and the soul and building solidarity.
4. Fasting in Ramadan
Muslims fast during Ramadan from dawn to sunset, abstaining from food, drink and other invalidators as an act of worship.
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ كُتِبَ عَلَيۡكُمُ ٱلصِّيَامُ كَمَا كُتِبَ عَلَى ٱلَّذِينَ مِن قَبۡلِكُمۡ لَعَلَّكُمۡ تَتَّقُونَ归信的人们啊！斋戒已成为你们的定制，犹如它曾为前人的定制一样，以便你们敬畏。
5. Hajj
A pilgrimage to Makkah in set days, required once in a lifetime for those who are physically and financially able. Muslims from every corner of the earth gather in simple, uniform garments.
فِيهِ ءَايَٰتُۢ بَيِّنَٰتٞ مَّقَامُ إِبۡرَٰهِيمَۖ وَمَن دَخَلَهُۥ كَانَ ءَامِنٗاۗ وَلِلَّهِ عَلَى ٱلنَّاسِ حِجُّ ٱلۡبَيۡتِ مَنِ ٱسۡتَطَاعَ إِلَيۡهِ سَبِيلٗاۚ وَمَن كَفَرَ فَإِنَّ ٱللَّهَ غَنِيٌّ عَنِ ٱلۡعَٰلَمِينَ其中有许多明证，如易卜拉欣的立足地。凡入其中的人都得安宁。凡能到它〔天房〕的人，都有为安拉而朝觐天房的义务。不归信的人，〔无损于安拉，〕因为安拉确是无求于众世界的。
