Combining the burial of martyrs without washing or shrouding with the lack of certainty regarding the martyrdom of a specific individual

Question:
The questioner asks: How do we reconcile the statement that they are buried at the place of their death without being washed or shrouded, with the statement of Ibn Mas'ud: "Do not say of the one who is killed between the two lines that he is a martyr, for you do not know in what state he was killed"?

Answer:
This is the position of the people of the Sunnah and the community. We do not assert with certainty that a specific person is a martyr; we do not know, but we hope that he is a martyr. We hope for him that he is a martyr. As for asserting it with certainty, that requires evidence from the Book of Allah. This is one of the chapters of creed. We do not declare anyone to be in Paradise or in the Fire, but we hope for the doers of good and we fear for the doers of evil.
