The reply was that if that were the case...
The reply was that if that were the case, he would have given some respite to men while he slept and in that period they would be safe! But we observe that man is not free from Satan's attacks. The educated reply is that Satan is not a physical being and it doesn't need any rest or sleep. The Signs of Satanic Attacks How would one know that the fears and doubts in the human hearts are the creations of Satan?
The reply is that every thought that a person gets that creates doubts and fears about Allah (S.w.T.), the Prophet (S.), about the Day of Reckoning and makes the person restless is the creation of Satan. As against this, every thought of trust on Allah (S.w.T.), belief on the eternal life, peace of heart and mind is Rahmani , or Godly, in origin.
Every doubt that takes one away from Allah (S.w.T.), deprives one of rewards, causes the visitation of Allah (S.w.T.)'s wrath is definitely the work of Satan. As against this, every thought that gives him the feeling of nearness to Allah (S.w.T.) and gives him the hope of Reward is purely Rahmani . The Rahmani Thoughts There are three types of thoughts that encompass the human mind on a continuous basis.
The first are those about which the person has definite information that they are legitimate and therefore Rahmani . For example: When the time for prayer arrives, the thought comes that he must pray. Or, when an opportunity comes for him to spend in the way of Allah (S.w.T.), the thought comes that he must do the good turn, Silat ar-Rahm , that someone has come to him asking for monetary help. Forgive such persons who have harmed him. Be fair in transactions.
In short, he gets thoughts about acts that are legitimate as per the commands of Allah (S.w.T.). The Satanic Thoughts The second category is composed by the thoughts that can be defined without any doubt of being satanic. They are all the exact opposite of the first category that we mentioned just now. In this category are all those fears and doubts that are contrary to the Shari’ah and wisdom.
For example: While spending in the way of Allah (S.w.T.) getting doubts that there is paucity of means for personal needs, Or he thinks whether it was necessary to incur the expense at that time. Perhaps a more essential need for spending might crop up later on. He may also think that another person is richer than him and more competent to provide help to the seeker than himself. If someone harmed him, he thinks of harming the person more in return.
