How can one respond to the false claims made against the religion, the Book of Allah, and the Messenger, may Allah bless him and grant him peace?

The struggle between truth and falsehood is a universal law, and the enemies will not cease to harm the sacred sites of Muslims unless Muslims abandon their religion. The doubts they raise do not affect Islam or its sacred sites, in fulfillment of His (the Almighty) saying: ﴿They want to extinguish the light of Allah with their mouths, but Allah refuses except to perfect His light, even if the disbelievers dislike it.﴾ Such people are like one who tries to weaken a rock by butting it; he does not harm it, but rather weakens his own horn.
