“One should not say: ‘So-and-so is a martyr.’” The Prophet, peace and blessings be upon him, said: “Allah knows best who strives in His cause, and Allah knows best who is wounded in His cause.” (1)
Umar ibn al-Khattab, may Allah be pleased with him, also forbade this. (2)
Yes, it may be said: Whoever is killed in the cause of Allah is a martyr, and whoever is killed by a collapsed building or by drowning is a martyr. But one must not testify to martyrdom for any particular individual.
