Aslaamulakum, I had a very disturbing dream regarding snakes. There was this man/ snake I cant fully recall which he was, but I remember seeing a large group ie hundreds of Muslim men and boys huddled together and he is sending many giant cobras through the water to attack these men and boys. They are all killed and I am very angry in the dream at this man and want to bring him to justice. He kills many boys and men and only Muslims.
Audhu billahi min ash-shaytan ir-rajim
Bismi-llāhi r-raḥmāni r-raḥīm:
Wa `alaykumu s-salāmu wa rahmatu l-lāhi wa barakātuh,
The man-snake represent dajjal and this dream is to show you that his appearance is near as well as the appearance of Sayyidina Mahdi (ʿalayhi s-salām).
To seek protection against dajjal and his army, the Holy Prophet (ṣall Allāhu ʿalayhi wa-sallam) said to learn and recite the first and last ten verses of Surat al-Kahf and to recite this du`a after the 2nd tashahhud and before taslim:
Allahumma inni a`udhu bika min `adhab al-qabr wa min `adhab al-nar
wa min al-fitani ma taqaddama minha wa ma ta’akhkhar wa min fitnat al-masih al-dajjal wa min fitnat al-mahya wa al mamat.
O Allah, I seek refuge in You from the punishment of the grave and from the punishment of the Fire and from tests and trials past and present and from the confusion of the anti-Christ and from the trial of life and death.
May Allah (swt) protect and save the Ummah from dajjal and his army, and Allah knows best.
