It is narrated from Sayyiduna Umar bin Khattab (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Every night the sea looks towards the land three times and seeks permission from Allah to overflow upon the people of the earth, but Allah restrains it.

People said to Sayyidina Ya'la (may Allah be pleased with him): Do you not see that Allah Almighty has said: For the wrongdoers, We have prepared a fire whose canopies will enclose them.
