وَٱلَّذِينَ يُؤْمِنُونَ بِمَآ أُنزِلَ إِلَيْكَ وَمَآ أُنزِلَ مِن قَبْلِكَ وَبِٱلْءَاخِرَةِ هُمْ يُوقِنُونَ
Wallatheena yu’minoona bimaa unzila ilayka wamaa unzila min qablika wabil aakhiratihum yooqinoon.
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].
Sura Al Baqarah: 4
This is the continuation of characteristics of the muttaqin. When ayah 3 covers spiritual and physical aspects, this ayah explains the meaning of the unseen in all dimensions of time i.e. past, present and future.
Belief in the Scriptures
Muttaqin are those who believed that all heavenly scriptures are sent by Allah.
1. By decreeing this, Allah ordered us to believe in all of His prophets as well. Indirectly, Allah wants us to put away our nationalism, tribalism and prejudices in dealing with other nations especially in inviting them to the straight path. This sets a clear guidelines for Muslim’s stand and policies with regard to non Muslims.
2. Also implied here is that no more kitab will come after Quran as Allah didnt command us to believe in future revelations, unlike covenant of bani Israel.
3. Belief in all the scriptures are contrary to the Christians and Jewish erroneous doctrines. When they were invited to follow Qur’an, they said they only believed in what their forefathers believed. This is not the teaching of previous prophets but their arrogance has overcame their cognition.
Belief in the Hereafter
1. Muttaqin are yaqin (truly certain, having knowledge free of doubts) that the Hereafter is true and coming.
In Islam, based on numerous ahadith, the Hereafter includes the resurrection from death, the reckoning, paradise and hellfire.
2. Indirectly, this implied that the world as we know is temporary.
