وَإِذَا مَرِضْتُ فَهُوَ يَشْفِينِ.
And when I am ill, it is He [Allah] who cures me.
Waidha mariḍtu fahuwa yashfin
While any affliction or disease is decreed by Allah, Prophet Ibraheem only verbally attributes the “healing” to Allah, out of his manners and veneration. In other words, he does not say, “And if He causes me to become ill, He cures me.”
