In the Bangladeshi community when one hears of some tragedy they recite 'Ina-lilahi-wa-ina-rajiun' (I'm not sure that I've transcribed that correctly.) Where does this phrase come from, and what does it mean, and how is it written in Arabic?
Inna lillahi wa inna ilayhi raji'un (إِنَّا لِلّهِ وَإِنَّـا إِلَيْهِ رَاجِعونَ) is a verse of the Quran which means Surely we belong to Allah and to Him shall we return.
This phrase is recited by Muslims when a person is struck by calamity in life, and is also recited upon hearing the death news of a Muslim. This can also be recited in any situation involving risk of any sort.
It is taken directly from the following ayah of the Qur'an:
الذين إذا أصابتهم مصيبة قالوا إنا لله وإنا إليه راجعون
Who, when disaster strikes them, say, "Indeed we belong to Allah , and indeed to Him we will return."
