The Qur'an and the sunnah of the prophet ( PBUH) inform us time and again that the final hour is close, without mentioning its appointed time. As for the knowledge of the time of the hours, it has not been given to any angel or prophet,. Nobody besides Allah knows when the final hours is. However certain sings and events are going to take place prior to the coming of the final hour, so that Muslims will take precaution against its trials and tribulations and be prepared for its coming.
