if you do not help him god has already helped him. when the unbelievers expelled him and he was one of the two people in the cave telling his friend do not worry god is with us then god gave him confidence and supported him with an army which you did not see and he defeated the cause of the disbelievers and made his own cause stand supreme. god is majestic and allwise.
إلا تنصروه فقد نصره الله إذ أخرجه الذين كفروا ثاني اثنين إذ هما في الغار إذ يقول لصاحبه لا تحزن إن الله معنا فأنزل الله سكينته عليه وأيده بجنود لم تروها وجعل كلمة الذين كفروا السفلى وكلمة الله هي العليا والله عزيز حكيم
