Allah Is All-Knowing
Unbelievers have always—and will always—slander believers. Likewise, their slanderous and hurtful words have never—and will never—harm believers, because Muslims know an important fact and so live their lives accordingly: Allah sees, knows, and hears everything. No one can bring the slightest harm to anyone else unless it is His will.
Every slanderous word is uttered within Allah’s knowledge and permission. When the slanderers hatch their plots, plan their conspiracies, and formulate their sentences, Allah is listening to and seeing them. Even when they utter the most slanderous words, thinking that they will force the Muslims to betray their religion, Allah knows what they are thinking, for as He reveals in the Qur’an:
Don’t you see that Allah knows what is in the heavens and on Earth? Three men cannot confer together secretly without Him being the fourth, or five without Him being the sixth, or fewer or more than that without Him being with them wherever they are. Then He will inform them on the Day of Resurrection of what they did. Allah has knowledge of all things. (Surat al-Mujadala, 7)
Or do they imagine that We do not hear their secrets and their private talk? On the contrary, Our messengers are right there with them writing it down! (Surat az-Zukhruf, 80)
As stated in these verses, no slanderer is ignored and no slanderous word, even if it was said only between two people, goes unheard. The slanderer may forget, but Allah, Who sees, hears, and creates it, never forgets. All the rebellious words and unfounded accusations spoken by the unbelievers, as well as all their evil thoughts and evil deeds, will meet them on the Day of Judgment, unless they repent of them.
Allah, the sole Ruler and Owner of all that exists, is the Muslims’ friend and guardian. Believers know that our Lord is infinitely compassionate and merciful, and that He creates everything in His wisdom in the best, most beneficial, and most just way possible. They trust and depend only on Him, and fear only Him. No slander, attack, threat, mockery, or attempt on their life or property will ever cause the believers to forsake the beauty of faith or to live by the Qur’an’s morality. Allah reveals the Muslim’s devotion and the rewards they will receive in return:
Among the believers are men who have been true to the contract they made with Allah. Some of them have fulfilled their pact by death, and some are still waiting to do so, not having changed in any way at all. So that Allah might recompense the faithful for their sincerity and punish the hypocrites, if He wills, or turn toward them. Allah is Ever-Forgiving, Most Merciful. Allah sent back those who disbelieved in their rage without their achieving any good at all...(Surat al-Ahzab, 23-25)
