Prophet Ilyās ﷺ (Elijah) was sent to the people of the northern kingdom of Israel who had turned to worshipping Baal (the idol of storms and fertility) under King Ahab and Queen Jezebel. He called them forcefully back to monotheism.
He was largely rejected and his people continued their idol worship. Allah saved and honoured him. The Quran praises him as one of the righteous and describes how future generations would continue to send peace upon him (Salām 'alā Ilyāsin).
