Allah's statement:

﴿وَلاَ تَقُولُواْ لِمَن يُقْتَلُ فِى سَبيلِ اللَّهِ أَمْوَاتٌ بَلْ أَحْيَاءٌ﴾

(And say not of those who are killed in the way of Allah, "They are dead.'' Nay, they are living,) indicates that the martyrs are alive and receiving their sustenance.

Muslim reported in his Sahih:

«أَنَّ أَرْوَاحَ الشُّهَدَاءِ فِي حَوَاصِلَ طَيْرٍ خُضْرٍ، تَسْرَحُ فِي الْجَنَّة حَيْثُ شَاءَتْ، ثُمَّ تَأْوِي إلَى قَنَادِيلَ مُعَلَّقَةٍ تَحْتَ الْعَرْشِ، فَاطَّلَعَ عَلَيْهِمْ رَبُّكَ اطِّلَاعَةً، فقَالَ: مَاذَا تَبْغُونَ؟ فَقَالُوا: يَا رَبَّنَا وَأَيَّ شَيْءٍ نَبْغِي، وَقَدْ أَعْطَيْتنَا مَا لَمْ تُعْطِ أَحَدًا مِنْ خَلْقِكَ؟ ثُمَّ عَادَ إِلَيْهِمْ بِمِثْلِ هذَا، فَلَمَّا رَأَوْا أَنَّهُم لَا يُتْرَكُون مِنْ أَنْ يُسْأَلُوا، قَالُوا: نُرِيدُ أَنْ تَرُدَّنَا إِلَى الدَّارِ الدُّنْيَا فَنُقَاتِلَ فِي سَبِيلِكَ حَتَّى نُقْتَلَ فِيكَ مَرَّةً أُخْرَى لِمَا يَرَوْنَ مِنْ ثَوابِ الشَّهادَةِ فَيَقُولُ الرَّبُّ جَلَّ جَلَالُهُ: إِنِّي كَتَبْتُ أَنَّهُمْ إلَيْهَا لَا يَرْجِعُون»

(The souls of the martyrs are inside green birds and move about in Paradise wherever they wish. Then, they take refuge in lamps that are hanging under the Throne (of Allah). Your Lord looked at them and asked them, `What do you wish for' They said, `What more could we wish for while You have favored us with what You have not favored any other of your creation' He repeated the question again. When they realize that they will be asked (until they answer), they said, `We wish that You send us back to the earthly life, so that we fight in Your cause until we are killed in Your cause again,' (because of what they enjoy of the rewards of martyrdom). The Lord then said, `I have written that they will not be returned to it (earthly life) again.)

Imam Ahmad reported that `Abdur-Rahman bin Ka`b bin Malik narrated from his father that Allah's Messenger said:

«نَسَمَةُ الْمُؤْمِنِ طَائِرٌ تَعْلَقُ فِي شَجَرِ الْجَنَّةِ حَتَّى يَرْجِعَهُ اللهُ إِلَى جَسَدهِ يَوْمَ يَبْعَثُه»

(The believer's soul is a bird that feeds on the trees of Paradise until Allah sends it back to its body when the person is resurrected.)

This Hadith includes all the believers in its general meaning. Thus, the fact that the Qur'an mentions the martyrs in particular in the above Ayah serves to honor, glorify and favor them (although the other believers share the rewards they enjoy).

﴿وَلَنَبْلُوَنَّكُم بِشَيْءٍ مِّنَ الْخَوفْ وَالْجُوعِ وَنَقْصٍ مِّنَ الاٌّمَوَالِ وَالاٌّنفُسِ وَالثَّمَرَتِ وَبَشِّرِ الصَّـبِرِينَ - الَّذِينَ إِذَآ أَصَـبَتْهُم مُّصِيبَةٌ قَالُواْ إِنَّا لِلَّهِ وَإِنَّـآ إِلَيْهِ رَجِعونَ - أُولَـئِكَ عَلَيْهِمْ صَلَوَتٌ مِّن رَّبْهِمْ وَرَحْمَةٌ وَأُولَـئِكَ هُمُ الْمُهْتَدُونَ ﴾

(155. And certainly, We shall test you with something of fear, hunger, loss of wealth, lives and fruits, but give glad tidings to As-Sabirin (the patient).) (156. Who, when afflicted with calamity, say: "Truly, to Allah we belong and truly, to Him we shall return.'') (157. They are those on whom are the Salawat (i.e., who are blessed and will be forgiven) from their Lord, and (they are those who) receive His mercy, and it is they who are the guided ones.)
