The Final War is to be fought in Al-sham
From the Hadith of Abu Hurayrah relates that the Prophet [peace and blessings of Allah be upon him] said, ‘’A group of my community will not cease to fight holding on to the order of Allah, the Almighty, the betrayal or desertion of whomever deserts them will not harm them in the least, fighting its enemies, every time a war ends, a war with another people will ensue, Allah will restrain away the hearts of a people to sustain them with it, until the Final Hour comes, like a portion of dark night, and they will get scared by it, until they shall wear for it shields’, and the Prophet (peace be upon him) said, ‘They are the people of Shaam’ and then the Prophet (peace be upon him) pointed with his finger to Shaam until he tired it’’ (Saheeh: Silsila al Ahadith As Saheeha)
Salamah bin Nufail (May Allah be pleased with him) said: While I was sitting with the Prophet (Peace be upon him) a man came to him and said, “O Messenger of Allah Horses are being humiliated (ignored), and weapons are being laid down and people are claiming there is no more Jihad and war has ended” the Prophet (Peace be upon him) said: “They are lying! Fighting has just begun! Fighting has just begun! And a party of my Ummah will remain fighting on the true path and Allah will deviate the hearts of some men and Allah will provide the fighters from them until the final hour starts and the promise of Allah is fulfilled and good is on the foreheads of horses until the Day of Judgment. It is being revealed to me that I will be departing you soon and you would follow me while you are fighting each other and the house of the believers is in al Shaam” (Al-Shaam refers to Syria, Lebanon, Palestine and Jordan. It could be used to refer to part or all of these countries. Narrated by Imam al-Nasa’i and is Hasan)
On the authority of ‘Abdullah bin Hawalah said: “O Messenger of Allah! Determine for me a land that I should live in, for if I knew that you would be with us for a long time, I would not choose anything over staying with you.” The Messenger of Allah (peace be upon him) said: “Go to Shaam, go to Shaam, go to Shaam.” So, when he saw that I disliked Shaam, he said: “Do you know what Allah – the Mighty and Majestic – Said? He Said: “You are the cream of My lands to which I enter the best of My servants.” (Narrated by Abu Dawud and Ahmad with a Sahih chain) And on the authority of Wasilah bin Al Asqa’ -May Allah be pleased with him- that the Prophet (peace be upon him) said: “Go to Shaam for it is the best of Allahs lands on earth, He drives the best of His slaves to it” (At Tabarani, and declared Sahih by Albani in Saheeh Al Jami)
