Islam is the religion of peace and love

The time of the coming of the Prophet Jesus (as) and Hazrat Mahdi (as) will be one of peace and security 

Verses from the Qur’an referring to Islam as the religion of peace, love and brotherhood: 

You who believe! Enter peace (Islam) totally. Do not follow in the footsteps of satan. He is an outright enemy to you. (Surat al-Baqara, 208) 

Allah calls to the Abode of Peace and He guides whom He wills to a straight path.... (Surah Yunus, 25)  

... if someone kills another person—unless it is in retaliation for someone else or for causing corruption in the earth—it is as if he had murdered all mankind. ... (Surat al-Maida, 32) 

The believers are brothers, so make peace between your brothers and fear Allah so that hopefully you will gain mercy. (Surat al-Hujurat, 10) 

Obey Allah and His Messenger and do not quarrel among yourselves lest you lose heart and your momentum disappear. And be steadfast. Allah is with the steadfast. (Surat al-Anfal, 46) 

As for those who believe and do right actions, the All-Merciful will bestow His love on them. (Surah Maryam, 96) 

You are the best nation ever to be produced before mankind. You enjoin the right, forbid the wrong and believe in Allah... (Surah Al ’Imran, 110) 

Make allowances for people, command what is right, and turn away from the ignorant. (Surat al-A’raf, 199)

Hadith Regarding the Prophet Jesus (as) Bringing Peace and Love to the World and Putting an End to Killing, Oppression and War: 

I swear that Jesus (as), son of Mary will descend as a just ruler... And all HOSTILITIES, QUARRELS, ENVY WILL ABSOLUTELY VANISH... (Al-Sharani, Mukhtasar Tazkirah al-Qurtubi, p. 498) 

Jesus (as), son of Mary will be a just judge and a just ruler, ... abolish the jizya (from the non-Muslims), FILL THE EARTH WITH PEACEjust as the water fills the pot. There will also be unity in religion and noone other than Allah will be worshipped anymore.(Sunan Ibn Majah, 10/334) 

The Prophet Jesus (as) exists in my community as a just ruler... ALL HOSTILITY AND HATRED VANISH... Earth becomes like a silver plate and grows the plants in abundance just like in the time of the Prophet Adam (as) ... (Al-Sharani, Mukhtasar Tazkirah al-Qurtubi, p. 496) 

EARTH WILL BE FILLED WITH PEACEjust like water fills the pot. NO HOSTILITY WILL REMAIN AND ALL HOSTILITIES, QUARRELS, ENVY WILL ABSOLUTELY VANISH.(Sahih Muslim, 1/136)

 Then he will live for 40 years. No one will die at his time. A person will tell his sheep and animals to go and graze, they will go and although they will pass through crops, they will take not a single ear of grain into their mouths. Snakes and scorpions will not harm anyone. Beasts will stand before the doors and will not harm anyone... (Jalaluddin as-Suyuti, Kıyamet alametleri, Olum ve Dirilis [Portents of the Judgment Day, Death and Resurrection],p 184)

ENMITY AND GRUDGEamong people will disappear. Scorpions and snakes will be without poison; even a child will play with a snake with bare hands without getting a snakebite. A girl will try to drive a lion but that lion will not touch her. A wolf will remain among sheep as if it were a shepherd

. As a bowl fills with water, the earth will fill with the unity of religion. People will worship no being other than Allah. NOTHING IN THE NAME OF WARS, STRIFE WILL REMAIN... The earth will be like a silver table. It will give off its plantations as it were in the time of Prophet Adam (as). A bunch of grapes will suffice a private. A group of people will be full with a single pomegranate. The price of an ox will be that much and a horse will be purchased in return for a dirham.

They said:

“The Messenger of Allah! Why will a horse be so cheap?”

“BECAUSE THERE WILL BE NO WAR, PEOPLE WILL NOT NEED IT MUCH!”

“Why will an ox will be so expensive?”

“Because the entire earth will be planted, it will be of great demand...” (Ibn Majah reported a similar one from Umama; Great Hadith Collection, al-Rudani, Vol. 5, p. 370-371-372)

Jesus (as) remains among the people as a just judge, an absolute judicious imam (religious leader) – ruler... ALL ENMITIES, GRUDGE

DISAPPEAR, the poison of each poisonous animal is drawn. Furthermore, a child puts his hand in the mouth of a snake but that snake does not give harm to it. A girl annoys a lion while caressing it but that lion does not give harm to the girl. A wolf becomes like a shepherd dog among a sheep herd. THE EARTH IS FILLED WITH PEACE AND SECURITY AS IF A BOWL IS FILLED WITH WATER. (At that time) a single word (the word of tawhid) remains and people worship only Allah. Warriors LEAVE THEIR LOAD (THAT IS THEIR ARMS, WEAPONS ETC.)(Al-Sharani, Mukhtasar Tazkirah al-Qurtubi, pp. 496-497) 

[Jesus (as)] will then live for forty years. AT HIS TIME NO ONE WILL DIE. A person will tell his sheep and animals to go and graze, they will go and although they will pass through crops, they will take not a single ear of grain into their mouths. Snakes and scorpions will not give harm to anyone. Predatory animals will lie at people’s doorsteps but they will not give harm to anyone. A person will take a scale of wheat and plant it [in a field] without ox and catapult, but he will still take seven hundred scales of wheat in return.(Jalaluddin as-Suyuti, Kıyamet alametleri, Olum ve Dirilis [Portents of the Judgment Day, Death and Resurrection],p. 184) 

“For seven years NO ONE WILL BE ENEMIES TO ONE ANOTHER.” (264- Ibn Manda, a.e II 958-9, al-Mukhaddas, a.E. Vr. 136-a 137-b) 

In his [Jesus’ (as)] time, earth brings out its treasures in its depths. People do not demand any possessions. Envy and grudge disappear. Allah clears off the poison of each poisonous being. Thus children play with snakes and scorpions, but they are not harmed. Wolves do not give harm to sheep. PEOPLE DO NOT KILL ONE ANOTHER. PEACE DOMINATES THE EARTH. Soil gives plenty of crops as it were in its initial days. (265- see Ahmad ibn Hanbal, Musnad, II, 409, 437; al-Safarini, Lavami, II 95) (Dr. Zeki Saritoprak, Jesus’ Descend from the Point of Islam, Cağlayan Press, Izmir, 1997, p. 96) 

THERE WILL BE NO PLACE FOR GRUDGE AND ENMITY AMONG PEOPLEsince the causes disappear... (Al-Barzanji, Al-Isha'ah li-ashrat al-sa'ah, pp. 242-243) 

“Jesus (as), son of Mary, will descend no matter what.”... “ENMITY, GETTING CROSS WITH EACH OTHER AND JEALOUSY WILL BE REMOVED.” (Abu Huraira, Great Hadith Collection, al-Rudani, Vol. 5, p. 379)
