O my people, enter the blessed land [i.e., Palestine] which Allāh has assigned to you and do not turn back [from fighting in Allāh's cause] and [thus] become losers."
Musa Reminds His People of Allah's Favors on Them; The Jews Refuse to Enter the Holy Land
Allah states that His servant, Messenger, to whom He spoke directly, Musa, the son of `Imran, reminded his people that among the favors Allah granted them, is that He will give them all of the good of this life and the Hereafter, if they remain on the righteous and straight path. Allah said,
(And (remember) when Musa said to his people: "O my people! Remember the favor of Allah to you, when He made Prophets among you,) for whenever a Prophet died, another rose among them, from the time of their father Ibrahim and thereafter. There were many Prophets among the Children of Israel calling to Allah and warning against His torment, until `Isa was sent as the final Prophet from the Children of Israel. Allah then sent down the revelation to the Final Prophet and Messenger, Muhammad ﷺ, the son of `Abdullah, from the offspring of Isma`il, the son of Ibrahim, peace be upon them. Muhammad is the most honorable Prophet of all times. Allah said next,
The saying of Sayyidna Musa (علیہ السلام) in the first verse (20) was his introductory remark to the Divine command which appears in the following verse (21) in the words: يَا قَوْمِ ادْخُلُوا الْأَرْضَ الْمُقَدَّسَةَ الَّتِي كَتَبَ اللَّـهُ لَكُمْ (0 my people, enter the Holy Land which Allah has destined for you ...).
Which land is the Holy Land?
Apparently, commentators differ about it. Some say that it means Baytul-Maqdis (Jerusalem). Some identify the city of Quds and Eliah as fitting the description of the Holy Land. Still others point out to the city of Ariha which was located between the Jordan river and Baytul-Maqdis and was reported to be one of the oldest cities of the world. In fact, it is still there. Unusual statements portraying its grandeur and vastness have been reported historically. Some narrations say that the city-was divided over one thousand wards or counties and every such section had some one thousand public gardens each. Then, there are other narrations which indicate that the Holy Land means Damascus and Palestine, or Jordan, according to some others. And Sayyidna Qatadah has said that the entire land of Syria is the Holy Land. Sayyidna Ka'b al-Ahbar has said that he has seen in the Book of Allah (perhaps, the Torah) that the country of Syria is a special treasure of Allah on this entire earth and there are in it Allah's very special and very dear servants. This land has been called ` holy' because it has been home to the blessed prophets of Allah. According to some narrations, on a day when Sayyidna Ibrahim (علیہ السلام) climbed a mountain in Lebanon, Allah Ta` ala said: 0 Ibrahim, look from here and as far as you will see, that land We have made the Holy Land. All narrations cited here have been taken from Tafsir Ibn Kathir and Tafsir Mazhari and the truth of the matter is that there is not much of a contradiction in these sayings. According to later narrations, the whole country of Syria is the Holy Land - it is just that some narrators have described a certain part of the country of Syria while some others have identified the whole of it.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 19–23
Considering any community as a favourite community of God is an absolutely meaningless thought. Before God the reckoning is individual to individual and not community to community. Everybody will get his reward before God according to his deeds. In the eyes of God, every man is a human being irrespective of his belonging to this community or that. Every man’s future will be decided on the basis of his performance in this world of test and trial. Paradise is not the native place of any community; nor is hell the prison for any particular community. It is the way of God that He, on His behalf, raises certain individuals who acquaint the people with the realities of life; warn them of hell and give them the good news of paradise. It is only by supporting these ‘warners’ and ‘bringers of good news’ and cooperating with them that man finds God, and not in any other way.
