I have read many signs concerning the appearance of the Mahdi, Dajjal, Prophet Isa. Signs that the Holy Prophet predicted. These signs have amazed me because they have almost all come true, or are happening at this moment. Signs such as time will pass quickly, drinking wine will increase, fornication will increase, singing will be common.. and so many more.
My question is, is that do you think that the coming of any of the three people named above is close and may it occur in our lifetime?

Muhammad the Messenger of Allah (Peace Be upon Him)
