The Language of Paradise is yet to be known but seems like everyone will conversate in whichever language they prefer.... It's Paradise, you'll get everything that you wish for in an instant. Some people are blinded by their hatred for Arabs and it considerably effects their judgement.You don't even have your facts straight.
Is Arabic the language of the people of Paradise?
I would like to know what the language of the people of Paradise is. Is it Arabic?.
Praise be to Allaah.
There is no mention in the Qur’aan or in the saheeh Sunnah – as far as we know – of which language is spoken by the people of Paradise. What is narrated concerning that is a hadeeth which is not soundly narrated from our Prophet (peace and blessings of Allaah be upon him), and some other reports (athaar).
It was narrated by al-Tabaraani in al-Awsat, al-Haakim, al-Bayhaqi in Shu’ab al-Eemaan and others that Ibn ‘Abbaas (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Love the Arabs for three reasons, because I am an Arab, the Qur’aan is Arabic and the speech of the people of Paradise is Arabic.”
Ibn al-Jawzi ruled that this hadeeth is fabricated. Al-Dhahabi said: I think that the hadeeth is fabricated (mawdoo’). Al-Albaani said in al-Silsilah al-Da’eefah (no. 160): (it is) fabricated.
...There is no basis for any of these ideas, whether on the grounds of common sense or in any report or text, rather they are mere claims that are devoid of any evidence. And Allaah knows best and is most Wise. End quote.
