Oh go on. I expect examples of speeches from the sahaba or prophet Muhammad otherwise your point is moot.Taking women and kids (السبي) of an army you had a fight with and then making them slaves for business (سوق النخاسة) and pleasure (ملك اليمين) is ok in your believe?
Do you seriously proofread and understand what you type before you post?
When Muslims invaded the Iberian peninsula, Tariq ibn Ziyad motivated his army with his infamous speech in which he said:
"وقد بلغكم ما أنشأت هذه الجزيرة من الحور الحسان، من بنات اليونان، الرافلات بالدر والمرجان، والحلل المنسوجة بالعقيان، المقصورات في قصور الملوك ذوي التيجان"
basically go ahead; get your share of white beautiful girls as slaves for pleasure. What war (justification) are you talking about? Are you saying Muslims are forced to take slaves just because they fought someone else?
