I have dealt with this matter previously and more here) but return to it after discovering this journal, The Syrian World, from which I found these two articles:-
You noticed the dates?
1927 and 1931.
Palestine is a province of Syria and Jerusalem is a Syrian city.
No Palestinianism, no unique Palestine Arab nationalism.
Indeed, into the late 1920s and even early 1930s, the Arab inhabitants of Syria who had immigrated to America, the intellectuals, considered Palestine a province of Syria and Jerusalem, a Syrian city.
A further indication is the Syrian-Palestinian Congress which was
the first serious attempt at challenging the French and British Mandates in the Middle East. It was called for in Geneva by a group of Syrian, Palestinian, and Lebanese exiled nationalists, headed by Prince Michel Lutfallah and bankrolled by Sharif Hussein, the King of the Hijaz. From left to right: Suleiman Kanaan, Tawfic Fayed, Najib Shuqayr, Amin al-Tamimi, Taan al-Imad, Assistant Secretary General of the Congress Tawfic al-Yazagi, Secretary-General Emir Shakib Arslan, Vice-President Mohammad Rashid Rida, Congress President Prince Michel Lutfallah, Vice-President Tawfic Hammad, George Yousef Salem, Ihsan al-Jabiri, Shibli al-Jamal, Salah Izziddine, Riad al-Sulh, Wahba al-Issa.
Moreover, it had a direct ramification on the idea of a separate "Palestine":-
The Syrian-Palestinian Congress, also known as the Syria-Palestine Congress or the Syro-Palestinian Congress was an organisation founded in June 1921 in Geneva by a group of Syrian and Palestinian exiles. The main aim of the congress was to try to influence the terms of the proposed League of Nations mandate over the region...The addition of Palestine to the name followed the Franco-British boundary agreement of December 1920 which formally defined the territory of Palestine out of the region viewed by the Pan-Syrian nationalists as Greater Syria. On 21 September, after twenty-six days of discussion, the joint congress issued a public statement to the League of Nations demanding, among other things, recognition of the "independence and national rule (al-Sultan al-Qawmi) of Syria, Lebanon and Palestine"
Note this from the NYTimes report:
