Sahl bin Hunaif (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "He who supplicates Allah sincerely for martyrdom, Allah will elevate him to the station of the martyrs, even if he dies on his bed."
[Muslim].
وعن سهل بن حنيف رضي الله عنه أن رسول الله ﷺ قال:
"من سأل الله تعالى الشهادة بصدق بلغه الله منازل الشهداء وإن مات على فراشه" ((رواه مسلم)).
