26 Preface أَن لا تَعبُدوا إِلَّا اللَّهَ ۖ إِنّي أَخافُ عَلَيكُم عَذابَ يَومٍ أَليمٍYusuf Ali“That ye serve none but God. Verily I do fear for you the penalty of a Grievous Day.”1Noah’s mission was to a wicked world, plunged in sin. The mission had a double character, as in the mission of all Prophets of God: it had to warn men against evil and call them to repentance, and it had to give them the glad tidings of God’s Grace in case they turned back to God: it was a Guidance and Mercy.
