How to protect ourselves from the false messiah Ad Dajjal?

Believers should know that taking protection everyday from the fitnah and trouble of the anti-Christ, is an important factor.

 

Allahumma inni a’udhu bika min ‘adhabi jahannam, wa min ‘adhabil-qabr, wa min fitnatil-mahya wal-mamat, wa min fitnatil-masihid-Dajjal.

 
O Allah! I seek Your protection from the torture of hell, and I seek Your protection from the torture of the grave, and I seek refuge with You from the mischief of life and death, and I seek Your protection from the mischief of Dajjal who is false Messiah.
 
 

The reciting of both the beginning and ending ten verses of Surat al-Kahf (the 18th sura of the Qur’an) has been transmitted from the Prophet (Allah bless him and give him peace). It is also recommended to recite the entire surah on Fridays.

 
Abu al-Darda’ (Allah be pleased with him) related that the Prophet of Allah (Allah bless him & give him peace) said, “Whoever commits ten verses from the beginning Surat al-Kahf will be protected from the Dajjal.” [Muslim, Abu Dawud, Nasa’i, and others; the wording is Muslim’s]…
 
In a narration in Muslim and Abu Dawud it states, “From the end of Surat al-Kahf.” Tirmidhi related is with the words, “Whoever recites three verses from the beginning of al-Kahf will be protected from the tribulations of the Dajjal.” [Mundhiri, al-Targhib wa’l Tarhib, #2172-2173]
 
Imam Shafi`i (Allah have mercy on him) said in his Umm,
“It has reached us that whoever recites Surat al-Kahf on Fridays will be protected from the Dajjal.” [Shafi`i, al-Umm, 1.239]
 
It is recommended to recite Surat al-Kahf completely the night before Friday, and it is also recommended to do so Friday itself, before Maghrib time. Ibn Abidin said, “And it is best to do so early on Friday, in order to rush to the good and to avoid forgetting.” [Ibn Abidin, Radd al-Muhtar, ‘Bab al-Jumu`ah’]
 
The evidence for it being recommended includes the hadith related by Hakim and Bayhaqi, from Abu Sa`id (Allah be pleased with him), “Whoever recites Surat al-Kahf on Friday, light shall shine forth for him between the two Fridays.” [Ibn Hajar, Talkhis al-Habīr]
 
The wisdom behind it, as mentioned by hadith commentators such as Nawawi, Qurtubi, Qari, and others, is that:
 
1) There are tremendous signs and portents mentioned in these verses. However reads these regularly and ponders on their meanings with not be led astray by the Dajjal;
 
2) The surah as a whole has stories of the struggle between true belief in Allah and the realities of faith, and materialism.
 
3) It is a secret whose knowledge Allah alone posses, and we have follow it because of the Prophet (Allah bless him and give him peace)’s guidance, with full certainty.
 
May Allah help our ummah from his threats and protect us all.

O Allah make us among those who are sincere
