Praise be to Allah.
You should note that the shaytaan is extremely keen to cause division between a man and his wife. It is narrated in a saheeh report that the Prophet (peace and blessings of Allaah be upon him) said: “Iblees places his throne on the water, then he sends out his troops, and those who are the closest in status to him are those who cause the most tribulation (fitnah). One of them comes and says, ‘I did such and such,’ and he says, ‘You have not done anything.’ Then one of them comes and says, ‘I did not leave him alone until I caused division between him and his wife.’ Then he brings him close to him and says, ‘How good you are.’” Narrated by Muslim, 5023.
In order for the shaytaan to reach this objective of his, there are many methods he uses to reach a man, one of which is creating doubt about his wife’s chastity.
You should also note that the fact that a woman does not bleed the first time she has intercourse does not necessarily mean that the woman has been unchaste, because the hymen may be elastic and there is no bleeding when intercourse takes place, as has been stated by doctors.
It may also be broken for many reasons other than intercourse, such as sports, jumping and so on.
Moreover, the blood that is usually expected may be only one or two drops, and this blood may come out mixed with other secretions, so the man does not see it because it is not visible.
For all of these reasons and others, it is not permissible for a man to doubt his wife’s chastity because she does not bleed when he first has intercourse with her. The fact that there is no bleeding does not mean that she is not chaste, just as the presence of bleeding does not mean that she is chaste, because some women have surgery to repair the hymen.
If your wife is a chaste woman and is religiously committed and of good character, then you should not let the shaytaan have any way of getting to you and spoiling your life. Seek refuge with Allaah from the accursed shaytaan, and do not doubt your wife without any clear proof.
May Allaah bless you both, and join you together in goodness, and divert the plot of the shaytaan away from you.
