The most meaningful text in the Islamic tradition to me right now is the following:

أللَّهُمَّ صَلِّ عَلَى مُحَمَّد وَآلِهِ، وَأَنْسِهِمْ عِنْدَ لِقَآئِهِمُ الْعَدُوَّ ذِكْرَ دُنْيَاهُمُ الْخَدَّاعَةِ الْغَرُورِ، وَامْحُ عَنْ قُلُوبِهِمْ خَطَرَاتِ الْمَالِ الْفَتُونِ، وَاجْعَلِ الْجَنَّةَ نَصْبَ أَعْيُنِهِمْ وَلَوِّحْ مِنْهَا لأِبْصَارِهِمْ مَا أَعْدَدْتَ فِيهَا مِنْ مَسَاكِنِ الْخُلْدِ وَمَنَازِلِ الْكَرَامَةِ وَالْحُورِ الْحِسَانِ وَالأَنْهَارِ الْمُطَّرِدَةِ بِأَنْوَاعِ الأَشْرِبَـةِ ، وَالأَشْجَارِ الْمُتَدَلِّيَةِ بِصُنُوفِ الثَّمَرِ، حَتَّى لاَ يَهُمَّ أَحَدٌ مِنْهُمْ بِالأدْبَارِ، وَلا يُحَدِّثَ نَفْسَهُ عَنْ قِرْنِهِ بِفِرَار

The meaning in English being:

O God, bless Muhammad and his Household

make the soldiers forget, when they meet the enemy, to remember this cheating and delusive world of theirs

erase from their hearts the thought of enchanting possessions

place the Garden before their eyes

display to their sight that part of it which You have prepared for them:

the homes of everlastingness and mansions of honour, the beautiful houris, the rivers gushing forth with all sorts of drinks, the trees hanging, low with all kinds of fruits

lest any of them think of turning his back

or suggest to himself to flee his opponent

Amen.
