It is He who sent down tranquillity into the hearts of the believers that they would increase in faith along with their [present] faith. And to Allah belong the soldiers of the heavens and the earth, and ever is Allah Knowing and Wise.
Tafseer
{ هو الذي أنزل السكينة } الطمأنينة { في قلوب المؤمنين ليزدادوا إيمانا مع إيمانهم } بشرائع الدين كلما نزَّل واحدة منها آمنوا بها ومنها الجهاد { ولله جنود السماوات والأرض } فلو أراد نصر دينه بغيركم لفعل { وكان الله عليما } بخلقه { حكيما } في صنعه، أي لم يزل متصفا بذلك .
{It is He who sent down tranquility} peace of mind {into the hearts of the believers that they would increase in faith along with their faith} in the laws of religion. Whenever He sent down one of them, they believed in it, including jihad. {And to God belong the soldiers of the heavens and the earth}. If He had wanted to support His religion through anyone other than you, He would have done so. {And God is Knowing} of His creation {Wise} in His creation, meaning He has always been characterized by that.
