Tafsir of Al-Fath 48:3

And that Allah may help you with strong help. (due to your obedience of the orders of Allah, the Exalted and Most Honored; Allah will elevate your status and give you victory above your enemies). An authentic Hadith states,

وما زاد الله عبدا بعفو إﻻ عزا وما تواضع أحد لله عز وجل إﻻ رفعه الله تعالى

No servant pardons but Allah grants him honor, and none humbles himself for Allah except that Allah the exalted and sublime raises him (in rank). Umar bin Al-Khattab said, "You will never punish someone who disobeyed Allah with you better than obeying Allah the Exalted and Most Honored with him.''
