QS al-Bayyinah: 98
The sura opens by condemning the polytheists of Arabia, as well as those amongst the People of the Book who had fallen into disbelief. However, they may be restored only by a "clear sign" from God who speaks holy and untainted words - the Prophet Muhammad SAW bringing the Qur'an, which lays down proper laws and morality. The fifth ayat explains that all God asks of mankind is - "To praise God by offering Him devotion being true, to pray the salat, and to give charity. And that is the Religion of Truth."... The mercy/rahmah of Allah SWT, subhaana-Allah! Those who cling to these simple truths will be offered the Gardens of Paradise, "underneath which rivers flow" as their prize; for God is pleased with them for being the best of possible creations. Those who turn away, however, shall meet the fires of Hell. Wallahu'alam bissawab.
