والَّذِينَ يُؤْمِنُونَ بِمَا أُنزِلَ إِلَيْكَ وَمَا أُنزِلَ مِن قَبْلِكَ وَبِالآخِرَةِ هُمْ يُوقِنُونَ
﴿٤﴾
سورة البقرة
(2/4) That they (the owners of piety) believe in what has been revealed to you and what was revealed before you (to all Holy Scriptures), and they believe in the Hereafter (that they will render their spirits back to Allah) at a certain level.
Surah Al-Baqarah
