Thus have We sent by inspiration to thee an Arabic Qur'an: that thou mayest warn the Mother of Cities and all around her,- and warn (them) of the Day of Assembly, of which there is no doubt: (when) some will be in the Garden, and some in the Blazing Fire. Ash-Shura 42:7 ⧉
Tafsir:
The real aim of the prophets’ call was to make the people conscious of the fact that they were going to be presented before God, after which, in accordance with their deeds, the decision in respect of some would be eternal Paradise, while in respect of others, it would be eternal Hell. The Prophet Muhammad came into this world to make people aware of this reality. His mission fell into two parts—one direct and the other indirect. His direct mission affected Makkah and the areas surrounding it. He completed this part of the mission during his lifetime. His indirect mission through his followers is for the whole world. This mission of his, still continues and will continue till Doomsday. The Prophet Muhammad presented his message to the Arab people in the Arabic language. After him, his followers too, as his deputies, have to fulfill their dawah responsibilities by adhering to the same principles. They are required to convey the message of Truth to every nation in its own language. Only when a nation is presented the message in its own language, will they be treated as having discharged the responsibility of conveying the message.
