The Prophet (peace and blessings be upon him) said:
"There are five things which no one knows except Allah: Indeed, with Allah alone is the knowledge of the Hour, and He sends down the rain, and He knows what is in the wombs, and no soul knows what it will earn tomorrow, and no soul knows in what land it will die. Indeed, Allah is All-Knowing, All-Aware."
