We humans are not expected to know the Unseen which no one but Allah knows. We can form our opinion about others only by their appearance, utterance and behavior.
7:187 (They even venture into predicting the end of the world.) They ask you (O Messenger), about the Hour, when the end of the world will come to pass. Say, "That knowledge is only with my Lord. He alone will manifest it at the appropriate time. Heavy it is in the heavens and earth. It will come upon you suddenly." They ask you as if you could gain insight into this mystery with a persistent inquiry. Say, “The knowledge thereof is with God only. But most people do not know” (that even Messengers were not given the knowledge of the Unseen except when God willed).
7:188 Say, "I do not even have the power to benefit myself or to avert harm from myself, contrary to the Laws of God. If I had the knowledge of the Unseen, I would have amassed an abundant fortune, and no adversity would have touched me. I am but a warner and a bearer of good news for those who have faith."
27:65 Say, “None in the heavens and the earth knows the Unseen, none whatsoever but God. Nor do they perceive when they will be raised.” [16:21]
35:38 Surely, God is Knower of the Unseen of the heavens and the earth and He is Knower of what is in the hearts.
72:25 Say, "I do not know whether the promise made to you is near or if my Lord will delay it."
72:26 Knower of the Unseen (and the future), and He makes known to none His secret,
72:27 Except as He wills to a Messenger whom He has elected, and to him He reveals from the past and the future, and ensures that the Revelation is guarded.
AVOID UNDUE SUSPICION
49:12 O You who have chosen to be graced with belief! Avoid suspicion, for, suspicion in some cases hurts your own ‘self’. ....... Be mindful of God. Certainly, God is Relenting, Merciful.
