There is an interesting book by the title "The Third World War and Dajal" the author lays out a detailed case on the concrete evidence of Hadith of Prophet Mohammad (PBUH) about the signs that will pave the way to Dajal.
It is a mesmerizing read and a haunting one. While reading I honestly felt that Dajal would come next weekend if not tommorow. So many of the signs which the Prophet (PBUH) listed that would pave the way for the great war and the coming of Hazrat Mahdi and then finally Dajal are happening in front of the eyes.
I list just a few.
1. The worst person in the country will be the country's leader.
2. Musical instruments and music will be common.
3. Alcohol will be widely and openly consumed.
Just these three are enough to make us realize that we are not very far from the great war and the day of judgement.
May Allah have mercy on all Muslims, lead us to the right path, stengthen our faiths and our backs. It is important that we follow the advice of the Propher Mohammad (PBUH) in such times and read Surah Kahf especially on Fridays if not the whole Surah then atlest the first 10 verses.
May Allah give us guidance and the will to do so.
