It is narrated from Sayyiduna Abu Bakrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The dread of the Messiah, the Dajjal, will not enter Madinah. On that day Madinah will have seven gates, and at each gate two angels (guardians) will be stationed."

It is narrated from Sayyiduna Sa'd bin Malik and Sayyiduna Abu Hurayrah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "O Allah! Bless the people of Madinah in their mudd and their sa' (measures), and bless them in their city. O Allah! Ibrahim (peace be upon him) was Your servant and Your intimate friend, and I am Your servant and Your Messenger. Ibrahim (peace be upon him) supplicated to You for Makkah, and I ask You for Madinah the same as Ibrahim (peace be upon him) asked for Makkah, and I ask for as much blessing again along with it. Take heed! Madinah is encircled by angels; at each of its routes there are two angels guarding it. Neither the plague nor the Dajjal can enter it. Whoever intends evil towards the people of Madinah, Allah will melt him just as salt melts in water." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Ubaydah bin al-Jarrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) mentioned the Dajjal and gave a description of him that I (the narrator) do not remember. The Companions said: O Messenger of Allah! Will the state of our hearts on that day be the same as it is today? He (peace and blessings be upon him) said: "Rather, it will be even better than that." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Ubaydah bin al-Jarrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There has been no prophet after Nuh (peace be upon him) who did not warn his nation about the Dajjal, and I too warn you about him." Then the Messenger of Allah (peace and blessings be upon him) described him to us and said: "You will find him, or someone who has seen me and heard from me will find him." We said: O Messenger of Allah! Will our hearts on that day be (in faith and steadfastness) as they are today? He (peace and blessings be upon him) said: "Rather, they will be even better than that."
