Doubt in the unseen matters, such as Paradise and the Fire, is apostasy from Islam

Question:
May Allah reward you with good, and may He do you good. After this, a message from one of our female listeners. The sender asks and says: I present this case to your eminence. It is that I have a friend who prays, fasts, and gives charity, but she has doubt in some matters of her religion. She doubts that there is a Paradise and a Fire. Also, she reads the Noble Qur'an, the Noble one, and she doubts the hadiths of the Messenger of Allah (peace and blessings be upon him), saying that they are old hadiths. I have advised her many times, but to no avail. What is your eminence's opinion? And what do you advise her and those like her? May Allah reward you with good.

Answer:
Perhaps this is from the whispers of Satan, from the whispers of Shaytan. And we engage in it. Whispers do not harm; if something from the whispers of Shaytan passes through a person's mind, it does not harm him, as the Prophet (peace and blessings be upon him) said: But if it is as mentioned in the question, doubt and hesitation, then this is apostasy from the religion of Islam. Doubt and hesitation, this is apostasy from the religion of Islam. But if it is mere whispering, and the person is sane and a believer, but some whispering occurs to him, then this does not harm him, and praise be to Allah. Yes.
