The station of martyrdom is granted to the one who makes a duʿāʾ for it regardless of how one dies
that the Prophet ﷺ said, "Who sought martyrdom with sincerity will be ranked by Allah among the martyrs even if he died on his bed."
أَنَّ النَّبِيَّ ﷺ قَالَ: «مَنْ سَأَلَ اللَّهَ الشَّهَادَةَ بِصِدْقٍ بَلَّغَهُ اللَّهُ مَنَازِلَ الشُّهَدَاءِ وَإِنْ مَاتَ عَلَى فِرَاشِهِ۔»
