He clarified "the dissolution of your oaths," which is His statement in Surah al-Ma'idah: "its expiation is the feeding of ten needy people" up to His statement: "then a fast of three days" (1).
His statement: "And Allah is your protector, and He is the All-Knowing" of His creation, "the All-Wise" in His command. Thus, the Messenger of Allah (peace be upon him) was commanded to perform the expiation, so he performed the expiation for his oath.
بيَّن ﴿تَحِلَّة أَيْمَانكُم﴾ وَهُوَ قَوْلُهُ فِي سُورَةِ الْمَائِدَةِ: ﴿فكفارته إطْعَام عشرَة مَسَاكِين﴾ إِلَى قَوْلِهِ: ﴿فَصِيَامُ ثَلاثَةِ أَيَّامٍ﴾ (١).
قَوْلُهُ: ﴿وَاللَّهُ مَوْلاكُمْ وَهُوَ الْعَلِيمُ﴾ بخلقه ﴿الْحَكِيم﴾ فِي أَمْرِهِ، فأُمرَ رَسُولُ اللَّهِ ﷺ بِالْكَفَّارَةِ فَكفر يَمِينه
