The Prophet (peace and blessings of Allaah be upon him) said:
There are three types of genes. One. Those who fly in the air. Two. Some snakes and dogs. Three. Comes to people and leaves.
(Source: Tabarani. Eminent Hadith scholar Shaykh Albani has called the hadith saheeh. See Saheeh Al Jame As Sagir, Hadith No. 3114, narrated from Abu Salaba Al Khashani.) (Muzammu Alfaz Al-Aqeedah)
Genes can take the form of different animals. But a group of them always move in human society in the guise of snakes and dogs. It is their permanent form.
3) Belief in the existence of jinn is a claim of faith
A Muslim must acknowledge the existence of jinn. If he denies the existence of jinn, then he will not be a believer. Acknowledging the existence of jinn involves believing in the unseen or invisible. Allah Almighty has discussed jinn about fifty times in the Qur'an. The creation of the jinn, the purpose of creation, their conversion to Islam, their creation before man, Iblis is one of the jinn, addressing the jinn and the people together in Surah Ar-Rahman, working for the jinn during the time of Prophet Solomon, masons and divers among them, their In the Qur'an, Allah Almighty has mentioned a lot of information about the punishment and reward of the Day of Judgment. Speaking about them, he revealed a complete Surah called Surah Al-Jinn. So no Muslim can deny the existence of jinn and deny the word of Allah. He can't even think of using the gene in a metaphorical sense. This is the creed of Ahl as-Sunnah wal Jamaat. The confused and extinct Mutazila and Jahmiya sects do not acknowledge the existence of jinn.
4) Do genes affect humans?
The answer is, of course, that jinn can seduce humans. Can go crazy by touch. Can rely on people. Can control him. It can disrupt the normal course of his life. It is to be believed. However, if one disbelieves in this matter, he cannot be called a disbeliever. He has made a mistake, it will be said. Some evidence of the jinn that makes people happy: Allah Almighty
Those who worship their Lord, they are not a nation except as a people who are disgusted by the devil from the messenger.
Those who eat usury will be like those whom the devil touches and drives mad. (Surat al-Baqara: 275)
All that is clearly understood by this verse:
One. Ideas about the type of punishment for those who take interest.
Two. Satan or jinn can drive people crazy by touching them.
Three. The touch of Satan or Jinn on human beings is a matter of truth. There is no way to deny it.
Four. By this touch of jinn-satan, man becomes spiritually damaged as well as physically abnormal.
Allaah says (interpretation of the meaning):
And for the one who turns away from the remembrance of the Most Merciful, I appoint a devil for him, so that he becomes his companion. (Surat al-Zukhruf: 36)
What is clear from this verse: The jinn refraining from the remembrance of the Most Gracious, the Most Merciful, is a reason for being harmed by the touch of Satan.
Allaah says (interpretation of the meaning):
And remember My servant Job, when he called to his Lord: "Satan has afflicted me with distress and torment." (Surah Saad: 41)
