Belief in the Last Day (Iman bil-Yawm al-Akhir) in the Holy Quran

﴿وَٱلَّذِينَ يُؤۡمِنُونَ بِمَآ أُنزِلَ إِلَيۡكَ وَمَآ أُنزِلَ مِن قَبۡلِكَ وَبِٱلۡأٓخِرَةِ هُمۡ يُوقِنُونَ ﴾ [Al-Baqarah: 4]

(4) And who believe in what has been revealed to you, [O Muhammad], and what was revealed before you, and of the Hereafter they are certain [in faith].

Surah: Al-Baqarah - Verse: 4 - Juz: 1 - Page: 2

﴿وَإِذۡ قَالَ إِبۡرَٰهِـۧمُ رَبِّ ٱجۡعَلۡ هَٰذَا بَلَدًا ءَامِنٗا وَٱرۡزُقۡ أَهۡلَهُۥ مِنَ ٱلثَّمَرَٰتِ مَنۡ ءَامَنَ مِنۡهُم بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِۚ قَالَ وَمَن كَفَرَ فَأُمَتِّعُهُۥ قَلِيلٗا ثُمَّ أَضۡطَرُّهُۥٓ إِلَىٰ عَذَابِ ٱلنَّارِۖ وَبِئۡسَ ٱلۡمَصِيرُ ﴾ [Al-Baqarah: 126]

(126) And [mention] when Abraham said, "My Lord, make this a secure city and provide its people with fruits - whoever of them believes in Allah and the Last Day." [Allah] said. "And whoever disbelieves - I will grant him enjoyment for a little; then I will force him to the punishment of the Fire, and wretched is the destination."

Surah: Al-Baqarah - Verse: 126 - Juz: 1 - Page: 19

﴿لَّٰكِنِ ٱلرَّٰسِخُونَ فِي ٱلۡعِلۡمِ مِنۡهُمۡ وَٱلۡمُؤۡمِنُونَ يُؤۡمِنُونَ بِمَآ أُنزِلَ إِلَيۡكَ وَمَآ أُنزِلَ مِن قَبۡلِكَۚ وَٱلۡمُقِيمِينَ ٱلصَّلَوٰةَۚ وَٱلۡمُؤۡتُونَ ٱلزَّكَوٰةَ وَٱلۡمُؤۡمِنُونَ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ أُوْلَٰٓئِكَ سَنُؤۡتِيهِمۡ أَجۡرًا عَظِيمًا ﴾ [An-Nisā’: 162]

(162) But those firm in knowledge among them and the believers believe in what has been revealed to you, [O Muhammad], and what was revealed before you. And the establishers of prayer [especially] and the givers of zakah and the believers in Allah and the Last Day - those We will give a great reward.

Surah: An-Nisā’ - Verse: 162 - Juz: 6 - Page: 103

﴿ ۞ أَجَعَلۡتُمۡ سِقَايَةَ ٱلۡحَآجِّ وَعِمَارَةَ ٱلۡمَسۡجِدِ ٱلۡحَرَامِ كَمَنۡ ءَامَنَ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ وَجَٰهَدَ فِي سَبِيلِ ٱللَّهِۚ لَا يَسۡتَوُۥنَ عِندَ ٱللَّهِۗ وَٱللَّهُ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلظَّٰلِمِينَ * ٱلَّذِينَ ءَامَنُواْ وَهَاجَرُواْ وَجَٰهَدُواْ فِي سَبِيلِ ٱللَّهِ بِأَمۡوَٰلِهِمۡ وَأَنفُسِهِمۡ أَعۡظَمُ دَرَجَةً عِندَ ٱللَّهِۚ وَأُوْلَٰٓئِكَ هُمُ ٱلۡفَآئِزُونَ ﴾ [At-Taubah: 19-20]

(19) Have you made the providing of water for the pilgrim and the maintenance of al-Masjid al-Haram equal to [the deeds of] one who believes in Allah and the Last Day and strives in the cause of Allah? They are not equal in the sight of Allah. And Allah does not guide the wrongdoing people.

(20) The ones who have believed, emigrated and striven in the cause of Allah with their wealth and their lives are greater in rank in the sight of Allah. And it is those who are the attainers [of success].

Surah: At-Taubah - Verse: 19-20 - Juz: 10 - Page: 189

﴿ٱلَّذِينَ يُقِيمُونَ ٱلصَّلَوٰةَ وَيُؤۡتُونَ ٱلزَّكَوٰةَ وَهُم بِٱلۡأٓخِرَةِ هُمۡ يُوقِنُونَ ﴾ [An-Naml: 3]

(3) Who establish prayer and give zakah, and of the Hereafter they are certain [in faith].

Surah: An-Naml - Verse: 3 - Juz: 19 - Page: 377

﴿وَمَا كَانَ لَهُۥ عَلَيۡهِم مِّن سُلۡطَٰنٍ إِلَّا لِنَعۡلَمَ مَن يُؤۡمِنُ بِٱلۡأٓخِرَةِ مِمَّنۡ هُوَ مِنۡهَا فِي شَكّٖۗ وَرَبُّكَ عَلَىٰ كُلِّ شَيۡءٍ حَفِيظٞ ﴾ [Saba’: 21]

(21) And he had over them no authority except [it was decreed] that We might make evident who believes in the Hereafter from who is thereof in doubt. And your Lord, over all things, is Guardian.
