And their prophet said to them “The sign of his kingship is that there will come to you the ark. Therein is a spirit of peace from your Lord and a remnant of what the folk of Moses and the folk of Aaron left behind the angels bearing it. Surely in that shall be a sign for you if you are believers.” Verily when God سبحانه makes a light appear He increases [that light] with the aid He provides directly from Himself. When Saul was made king over them the doubt about his qualification was eliminated by the appearance of [God's] signs that proved the veracity of the words of their prophet [declaring God's choice of Saul]. He returned the ark which contained the spirit of peace sakīna to them. Thus the sign of his kingship became clear to them with the fact that their prophet عليه السلام had spoken truly to them in what he told them. It is said that God most high placed the spirit of peace sakīna of the children of Israel in the ark that contained the shards of the tablets and the rod of Moses عليه السلام and [other] relics of their prophets. He placed the spirit of peace of [Muḥammad's] community in their hearts: He it is who sent down the spirit of peace into the hearts of the believers [48:4]. Moreover the ark circulated in the hands of enemies and others. One time it was buried another time it was seized and carried away another time it was returned and another time [and so on... ]. But as for the hearts of the believers-[God] comes between the possessors [of these hearts] and [the spirit of peace]. He did not entrust it to a king or a prophet or to the heavens or air or to a place or person. The Prophet ﷺ said “The heart of the believer is between the two fingers of the Merciful” meaning in the grasp of the Real سبحانه and under His domination taghlīb and disposal taṣrīf. This means it is the divine power of deliberation qudra. What a difference between a community whose spirit of peace is in what enemies can control and a community whose spirit of peace is in that over which no created being has any control!
