by the permission of allah they routed them. david slew goliath and allah bestowed on him the kingship and wisdom and taught him from that he willed. had allah not pushed the people some by the other the earth would have been corrupted. but allah is bountiful to the worlds.
فهزموهم بإذن الله وقتل داوود جالوت وآتاه الله الملك والحكمة وعلمه مما يشاء ولولا دفع الله الناس بعضهم ببعض لفسدت الأرض ولكن الله ذو فضل على العالمين
