قَالَ مُوسَىٰ لِقَوْمِهِ ٱسْتَعِينُوا۟ بِٱللَّهِ وَٱصْبِرُوٓا۟ ۖ إِنَّ ٱلْأَرْضَ لِلَّهِ يُورِثُهَا مَن يَشَآءُ مِنْ عِبَادِهِۦ ۖ وَٱلْعَٰقِبَةُ لِلْمُتَّقِينَ
And Moses said unto his people: Seek help in Allah and endure. Lo! the earth is Allah's. He giveth it for an inheritance to whom He will. And lo! the sequel is for those who keep their duty (unto Him).

Sahih al-Bukhari
Fighting for the Cause of Allah (Jihaad)
Chapter: The wish for martyrdom
Narrated Anas bin Malik:
The Prophet (ﷺ) delivered a sermon and said, "Zaid took the flag and was martyred, and then Ja`far took the flag and was martyred, and then `Abdullah bin Rawaha took the flag and was martyred too, and then Khalid bin Al-Walid took the flag though he was not appointed as a commander and Allah made him victorious." The Prophet (ﷺ) further added, "It would not please us to have them with us." Aiyub, a sub-narrator, added, "Or the Prophet, shedding tears, said, 'It would not please them to be with us.'"
