We all know God Almighty does everything. And no one else does or can really do anything.
Teachers are nothing but means that Allah uses to educate us.
When he wants to, he can take a most uneducated human on earth -- call him The Unlettered Man if you will -- and use him to educate the whole world. As he did with Sayyidina Muhammad, Sallallahu Alaihi wa Sallam!
Parents are nothing but a way to create human life on earth.
If God Almighty were to wish, he can make a baby without a father, as he did with Jesus, Alaihis Salam, or a full-grown man without either a father or a mother, the way he did with Adam, Alaihis Salam.
Transportation, vehicles, animals, machines, are all nothing but means to carry objects, human or otherwise, from Point A to Point B.
Were God to wish, he could transport a man from the middle of the desert in Makkah, around 7th Century, and whisk him off to Jerusalem, miles and miles and miles away, and from there all the way up into space, beyond Moon, Mars and the Galaxies, to the heavens beyond, and back, all before the night is out and before the cock crows.
Was that precisely not what God Almighty did with Prophet Muhammad, Sallallahu Alaihi wa Sallam, during Israa' and Mi'raj?
How well do we know that doctors and medicines are nothing but merely means to healing!
Should God Almighty please, he can make a fountain of water gush out from under your feet, and make that water a cure for all your ailments as he did with Ayyub, Alaihis Salaam.
And yet, how little we seem to care!
And how little we seem to believe!
Qaleelalan Ma Tu'minoon!
And how sad and pitiable are our ways and attitudes as humans beings!
Yaa Hasratan Alal Ibaad!
