GodlyVerses

O you who have believed, what is [the matter] with you that, when you are told to go forth in the cause of Allah, you adhere heavily to the earth? Are you satisfied with the life of this world rather than the Hereafter? But what is the enjoyment of worldly life compared to the Hereafter except a [very] little. - Quran At-Tawbah(The Repentance) 9:38 (islam)

Fight them; Allah will punish them by your hands and will disgrace them and give you victory over them and satisfy the breasts of a believing people - Quran At-Tawbah(The Repentance) 9:14 (islam)

The Prophet (ﷺ) said, "The person who participates in (Holy battles) in
Allah's cause and nothing compels him to do so except belief in Allah
and His Apostles, will be recompensed by Allah either with a reward,
or booty (if he survives) or will be admitted to Paradise (if he is
killed in the battle as a martyr). Had I not found it difficult for my
followers, then I would not remain behind any sariya going for Jihad
and I would have loved to be martyred in Allah's cause and then made
alive, and then martyred and then made alive, and then again martyred
in His cause."
- Hadith Al Bukhari 36 (islam)

The Prophet (ﷺ) said, "Nobody who dies and finds good from Allah (in the
Hereafter) would wish to come back to this world even if he were given
the whole world and whatever is in it, except the martyr who, on
seeing the superiority of martyrdom, would like to come back to the
world and get killed again (in Allah's Cause)." - Hadith Al Bukhari 2795 (islam)

So let those fight in the cause of Allah who sell the life of this world for the Hereafter. And he who fights in the cause of Allah and is killed or achieves victory - We will bestow upon him a great reward. - Quran An-Nisa(The Women) 4:74 (islam)

“There is no one who is wounded in the cause of Allah – and
Allah
knows best of who is wounded in His cause – but he will come on
the
Day of Resurrection with his wounds looking as they did on the day
he
was wounded; their color will be the color of blood but their smell
will be the fragrance of musk.” - Hadith Ibn Majah 2795 (islam)

And if you are killed in the cause of Allah or die - then forgiveness from Allah and mercy are better than whatever they accumulate [in this world]. - Quran Ali 'Imran(The Family of Imran) 3:157 (islam)

And do not say about those who are killed in the way of Allah, "They are dead." Rather, they are alive, but you perceive [it] not. - Quran Al-Baqarah(The Cow) 2:154 (islam)

A man came to Allah's Messenger (ﷺ) and said, "Instruct me as to such a deed as equals Jihad (in reward)."
He replied, "I do not find such a deed." Then he added, "Can you, while the Muslim fighter is in the
battle-field, enter your mosque to perform prayers without cease and fast and never break your fast?"
The man said, "But who can do that?" Abu- Huraira added, "The Mujahid (i.e. Muslim fighter) is
rewarded even for the footsteps of his horse while it wanders bout (for grazing) tied in a long rope." - Hadith Al Bukhari 2785 (islam)

Book 20, Hadith 3110

We asked 'Abdullah about the Qur'anic verse:" Think not of those who are slain in Allah's way as dead. Nay, they are alive, finding their sustenance in the presence of their Lord.." (iii. 169). He said: We asked the meaning of the verse (from the Holy Prophet) who said: The souls, of the martyrs live in the bodies of green birds who have their nests in chandeliers hung from the throne of the Almighty. They eat the fruits of Paradise from wherever they like and then nestle in these chandeliers. Once their Lord cast a glance at them and said: Do ye want anything? They said: What more shall we desire? We eat the fruit of Paradise from wherever we like. Their Lord asked them the same question thrice. When they saw that they will continue to be asked and not left (without answering the question). they said: O Lord, we wish that Thou mayest return our souls to our bodies so that we may be slain in Thy way once again. When He (Allah) saw that they had no need, they were left (to their joy in heaven). - Hadith Muslim 1887 (islam)
Book 33, Hadith 181
Book 20, Hadith 4651

That the Messenger of Allah (ﷺ) said: "To go out in the cause of Allah in the morning, or the afternoon, is better than the world and what is in it. And the space that a bow of one of you - or the space that his hand - would occupy in Paradise is better than the world and what is in it. And if a woman among the women inhabiting Paradise were to appear to the people of the earth, then she would illuminate what is between the ( the heavens and the earth), and a pleasant scent would fill up what is between them, and the scarf on her head is better than the world and what is in it."
[Abu 'Eisa said:] This Hadith is Hasan Sahih.
