Someone close to me is in the process of committing adultery. She has confided about it to someone close to me, who is a very reliable source. However when we confronted her she denied it. Is it permissible in Islam that we as her family can spy on her to attain evidence of her meeting another man so that we can confront her. We feel if we do not do something now her kids and entire family will suffer. Her husband seems to be blind to what is going on, even though it has been hinted to him. Please tell me what I can do?


All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad  sallallaahu  `alayhi  wa  sallam ( may  Allaah exalt his mention ) is His slave and Messenger.

Allah Says (what means): {And do not spy or backbite each other.} [Quran 49: 12]

Abu Hurayrah  may  Allaah  be  pleased  with  him narrated that the Prophet  sallallaahu  `alayhi  wa  sallam ( may  Allaah exalt his mention ) said: “Beware of suspicion, for suspicion is the worst of false tales, and do not look for the others' faults, and do not spy on one another, and do not be jealous of one another, and do not desert (stop talking) to one another, and do not hate one another. And be Allah's slaves and brothers.” [Al-Bukhari and Muslim]

Allah and his Prophet  sallallaahu  `alayhi  wa  sallam ( may  Allaah exalt his mention ) forbade spying and looking for the faults of Muslims, instead we are ordered to think well of them and to cover them. However, if a person wants to be alone with a woman for the purpose of adultery, spying is permissible as approved by the scholars, to protect the woman from indulging in illegal sex.
Imam Ibn Haja  may  Allaah  have  mercy  upon  him wrote in the explanation of Saheeh Al-Bukhari: “Spying to save a life, such as if one comes to know from a trustworthy person that someone is in seclusion with someone to kill him unjustly, or with a woman to have illegal sex with her, then spying is permissible to prevent harm before it is too late. Such cases are exempted from the general prohibition of spying. This is reported from Al-Mawardi by Imam An-Nawawi who considered it a good opinion.

If one knows about a woman that she wants to have illegal sex with a man, then he/she should exhort her, advice her to avoid it, and should cover her. If she makes her sin public and does not feel shame, then it is compulsory to inform the one who can deter her from this act.

Allah knows best.
