Quran 98:4 — Proof (Al-Bayyinah)

In fact, those who received the scripture did not dispute until the proof was given to them.

[98:3] In them there are valuable teachings.

[98:5] All that was asked of them was to worship GOD, devoting the religion absolutely to Him alone, observe the contact prayers (Salat), and give the obligatory charity (Zakat). Such is the perfect religion.
