In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Allaah [The Exalted] said: [يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ ٱصۡبِرُواْ وَصَابِرُواْ وَرَابِطُواْ وَٱتَّقُواْ ٱللَّهَ لَعَلَّكُمۡ تُفۡلِحُونَ – O you who believe! Endure and be more patient (than your enemy), and guard your territory by stationing army units permanently at the places from where the enemy can attack you, and fear Allah, so that you may be successful. [Surah Aal Imraan. Verse 200]
The Messenger of Allaah [peace and blessings of Allaah be upon him] said, “To guard Muslims (from the enemy) in Allah’s Cause for one day is better than the world and whatever is on its surface, and a place in Paradise as small as that occupied by the whip of one of you is better than the world and whatever is on its surface; and a morning’s or an evening’s journey which a slave (person) travels in Allah’s Cause is better than the world and whatever is on its surface”. [Saheeh al-Bukhaari 2892]
