It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: Hazrat Isa (peace be upon him) will descend as a just leader and fair ruler. He will break the cross, kill the swine, restore peace, and swords will be made into sickles. The sting of every stinging creature will be removed. The sky will send down its sustenance, and the earth will bring forth its blessings, so much so that children will play with snakes and the snakes will not harm them. The wolf will guard the goats and will not harm them, and a lion will look after cattle and it will not harm them.
