As Saff, 4 Ayah
61:4
إِنَّ ٱللَّهَ يُحِبُّ ٱلَّذِينَ يُقَٰتِلُونَ فِي سَبِيلِهِۦ صَفّٗا كَأَنَّهُم بُنۡيَٰنٞ مَّرۡصُوصٞ ٤
'Inna Al-Laha Yuĥibbu Al-Ladhīna Yuqātilūna Fī Sabīlihi Şaffāan Ka'annahum Bunyānun Marşūşun
Indeed, Allah loves those who fight in His cause in a row as though they are a [single] structure joined firmly.
