Are martyrs dead or alive?
The view that martyrs are alive is based on the evidences from the Holy Qur'an. Surah al-Baqarah (2) reads:
And say not of those who are slain in the way of Allah. "They are dead." Nay, they are living, though ye perceive (it) not. (Q 2:154)
وَلاَ تَقُولُوْا لِمَنْ يُقْتَلُ فِي سَبيلِ اللّهِ أَمْوَاتٌ بَلْ أَحْيَاء وَلَكِن لاَّ تَشْعُرُونَ (154:2)
Similarly, a verse from Surah 'Āl 'Imrān reads as follows:
Think not of those who are slain in Allah.s way as dead. Nay, they live, finding their sustenance in the presence of their Lord. (Q 3:169)
وَلاَ تَحْسَبَنَّ الَّذِينَ قُتِلُوْا فِي سَبِيلِ اللّهِ أَمْوَاتًا بَلْ أَحْيَاء عِندَ رَبِّهِمْ يُرْزَقُونَ (169:3)
The verse in Surah Baqarah explicates that we cannot perceive the reality of that life. It clearly shows that their life is different from that of ours. We cannot grasp the essence and form of their life comparing it with our everyday life.
