For

God Almighty said about the one whom I love with the love of voluntary prayers, you are his hearing, his sight, and his tongue that speaks

And God testified to Muhammad, may God bless him and grant him peace, that he has a voluntary prayer, according to the Almighty’s saying, and from the night, so he performed Hajj. It is voluntary for you. His hearing must be the truth, his sight is the truth, and his speech is the truth, and no one among creation testified to it as being appointed. So the sign of someone whose obligatory duties are not exhausted by his voluntary deeds and for whom voluntary deeds are preferred is that God Almighty loves him this special love and makes its sign that the truth be their hearing, their sight, their hands, and all their powers, and for this reason the Messenger of God called upon May God’s prayers and peace be upon him, that all of it be light, for God is the light of the heavens and the earth .
