وَأَقِيمُواْ ٱلصَّلَوٰةَ وَءَاتُواْ ٱلزَّكَوٰةَۚ وَمَا تُقَدِّمُواْ لِأَنفُسِكُم مِّنۡ خَيۡرٖ تَجِدُوهُ عِندَ ٱللَّهِۗ إِنَّ ٱللَّهَ بِمَا تَعۡمَلُونَ بَصِيرٞ
And perform As-Salat (Iqamat-as-Salat), and give Zakat, and whatever of good (deeds that Allah loves) you send forth for yourselves before you, you shall find it with Allah. Certainly, Allah is All-Seer of what you do.
وَقَالُواْ لَن يَدۡخُلَ ٱلۡجَنَّةَ إِلَّا مَن كَانَ هُودًا أَوۡ نَصَٰرَىٰۗ تِلۡكَ أَمَانِيُّهُمۡۗ قُلۡ هَاتُواْ بُرۡهَٰنَكُمۡ إِن كُنتُمۡ صَٰدِقِينَ
And they say, "None shall enter Paradise unless he be a Jew or a Christian." These are their own desires. Say (O Muhammad Peace be upon him), "Produce your proof if you are truthful."
بَلَىٰۚ مَنۡ أَسۡلَمَ وَجۡهَهُۥ لِلَّهِ وَهُوَ مُحۡسِنٞ فَلَهُۥٓ أَجۡرُهُۥ عِندَ رَبِّهِۦ وَلَا خَوۡفٌ عَلَيۡهِمۡ وَلَا هُمۡ يَحۡزَنُونَ
Yes, but whoever submits his face (himself) to Allah (i.e. follows Allah's Religion of Islamic Monotheism) and he is a Muhsin (good-doer i.e. performs good deeds totally for Allah's sake only without any show off or to gain praise or fame, etc., and in accordance with the Sunnah of Allah's Messenger Muhammad Peace be upon him) then his reward is with his Lord (Allah), on such shall be no fear, nor shall they grieve.
