This Is My Faith - Al-fatlawi, Ali - الصفحة ٣٢٩ - The Meaning of the Hereafter (Mi’ad)
Anwar: Will you elaborate more, please?
Hasan: Yes. When one dies, they go to the world of Barzakh, which is a world between this world and the next world. Now, if they are believers, they will live in happiness and bounty; but, if they were infidels or disobedient, they will live in agony and pain.
The following Holy Verse is evidence to the life of martyrs who scarified themselves for the sake of the Most Gracious Allah:
(And reckon not those who are killed in Allah's way as dead; nay, they are alive (and) are provided sustenance from their Lord۞Rejoicing in what Allah has given them out of His grace and they rejoice for the sake of those who, (being left) behind them, have not yet joined them, that they shall have no fear, nor shall they grieve)٣;١٦٩-١٧٠.
There is a clear reference in this Holy Verse to the joyful life of the martyrs. This next Holy Verse plainly talks about the Purgatory (Barzakh) life:
(…and before them is a barrier until the day they are raised)٢٣;١٠٠.
