The Messenger of Allah ﷺ said, "Military expeditions are of two kinds. As for the one who sets out seeking the face of Allah, obeys the leader, spends what is dear to him, treats his companion with ease, and avoids corruption, his sleep and his wakefulness are all a reward for him. But as for the one who goes out to fight for boasting, showing off, and reputation, who disobeys the leader and spreads corruption in the land, he does not return even breaking even."
حدثنا حيوة بن شريح ويزيد بن عبد ربه قالا ثنا بقية وهو ابن الوليد حدثني بحير بن سعد عن خالد بن معدان عن أبي بحرية
عن رسول الله ﷺ أنه قال الغزو غزوان فأما من ابتغى وجه الله وأطاع الإمام وأنفق الكريمة وياسر الشريك واجتنب الفساد فإن نومه ونبهه أجر كله وأما من غزا فخرا ورياء وسمعة وعصى الإمام وأفسد في الأرض فإنه لم يرجع بالكفاف
