Al-An'am (The Cattle)
Surah 6 · Verse 111
And even if We had sent down angels to them, and the dead had spoken to them, and We had gathered for them every thing in front of them, (even then) they would not believe unless Allah wills it, and the majority of them is ignorant.
Firawn and his followers did not believe even after witnessing the miracles performed through Musa (PBH), Ibrahim (PBH) broke the idols and presented a very convincing proof and argument still his community did not believe. Therefore it is obvious that people do not believe because of miracles, proofs or arguments but they believe only when Allah (SWT) wills. Many people do not know this secret.
