A shahid is considered one whose place in
Paradise is promised according to these verses in the
Quran:
The
Quran,
chapter 3 (
Al Imran),
verse 169–170:
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; They rejoice in the bounty provided by Allah. And with regard to those left behind, who have not yet joined them (in their bliss), the (Martyrs) glory in the fact that on them is no fear, nor have they (cause to) grieve. — translated by
Abdullah Yusuf Ali
The
Quran,
chapter 9 (
At-Tawba),
verse 111:
Allah hath purchased of the believers their persons and their goods; for theirs (in return) is the garden (of Paradise): they fight in His cause, and slay and are slain: a promise binding on Him in truth, through the Law, the
Gospel, and the Qur´an: and who is more faithful to his covenant than Allah? then rejoice in the bargain which ye have concluded: that is the achievement supreme. — translated by
Abdullah Yusuf Ali
The Quranic passage that follows is the source of the concept of Muslim martyrs being promised Paradise:
The
Quran,
chapter 22 (
Al-Hajj),
verse 58:
Those who leave their homes in the cause of Allah, and are then slain or die,- On them will Allah bestow verily a goodly Provision: Truly Allah is He Who bestows the best provision. — translated by
Abdullah Yusuf Ali
Hadiths
The importance of faith is highlighted in the following hadith:
It has been narrated on the authority of Anas b. Malik that the Messenger of Allah (may peace be upon him) said: Who seeks martyrdom with sincerity shall get its reward, though he may not achieve it.

Muslim ibn al-Hajjaj, "
Sahih Muslim"
[4]
It is thus not the outcome that determines the placement in Heaven but rather the intention.
Nonetheless, Paradise for a Shahid is a popular concept in the Islamic tradition according to Hadith, and the attainment of this title is honorific.
The
prophet Muhammad is reported to have said these words about martyrdom:
By Him in Whose Hands my life is! I would love to be martyred in Allah's Cause and then get resurrected and then get martyred, and then get resurrected again and then get martyred and then get resurrected again and then get martyred.

Muhammad al-Bukhari,
Sahih al-Bukhari[5]
The Prophet said, "Nobody who enters Paradise likes to go back to the world even if he got everything on the Earth, except a Mujahid who wishes to return to the world so that he may be martyred ten times because of the dignity he receives (from Allah).
— Collected by
Muhammad al-Bukhari,
Sahih al-Bukhari[6]
Several hadith also indicate the nature of a Shahid's life in Paradise. Shahids are thought to attain the highest level of Paradise, the Paradise of al-Firdous.
Haritha was martyred on the day (of the battle) of Badr, and he was a young boy then. His mother came to the Prophet and said, "O Allah's Apostle! You know how dear Haritha is to me. If he is in Paradise, I shall remain patient, and hope for reward from Allah, but if it is not so, then you shall see what I do?" He said, "May Allah be merciful to you! Have you lost your senses? Do you think there is only one Paradise? There are many Paradises and your son is in the (most superior) Paradise of Al-Firdaus.

Furthermore, Samura narrated:
The Prophet said, "Last night two men came to me (in a dream) and made me ascend a tree and then admitted me into a better and superior house, better of which I have never seen. One of them said, 'this house is the house of martyrs.'

Muhammad al-Bukhari,

There are at least five different kinds of martyrs according to hadith.
Allah's Apostle said, "Five are regarded as martyrs: They are those who die because of plague, abdominal disease, drowning or a falling building etc., and the martyrs in Allah's cause.

One who dies protecting his property is also considered a martyr according to Hadith:
I heard the Prophet saying, "Whoever is killed while protecting his property then he is a martyr.
— Collected by
Muhammad al-Bukhari,
Sahih al-Bukhari[10]
While the Qur'an does not indicate much about martyrs' death and funeral, the hadith provides some information on this topic. For example, martyrs are to be buried two in one grave in their blood, without being washed or having a funeral prayer held for them. The following Hadith highlight this:
The Prophet collected every two martyrs of Uhud in one piece of cloth, then he would ask, "Which of them had (knew) more of the Quran?" When one of them was pointed out for him, he would put that one first in the grave and say, "I will be a witness on these on the Day of Resurrection." He ordered them to be buried with their blood on their bodies and they were neither washed nor was a funeral prayer offered for them.

So it is 100% Islamic terminology used by Muslims only. Now tell me where are you standing?. By calling them Shaheed means you are calling them Muslims, are you agree on that?
