The Shaykh : There may be a barrier that prevents its effectiveness and the occurrence of the result. This is the most correct view: it is general, and it does not harm him, neither in his body nor in his heart. However, this falls under the category of causes, and causes may have barriers. Just as the causes of inheritance exist—such as a person being a relative, a spouse, or a freed slave—barriers may also exist that prevent these causes from taking effect. The general rule is that things are not completed unless their causes and conditions are fulfilled and their barriers are removed. If we apply this rule to this hadith and similar ones, we say that this is from the Messenger of Allah (peace and blessings be upon him) to clarify the cause. Then, barriers may exist that prevent this cause from taking effect. For example, this child may live after his birth in a bad environment, which may divert him from righteousness, as the Prophet (peace and blessings be upon him and his family) said: This hadith encourages making this dhikr during intercourse with one’s wife, because it possesses this great benefit, which would be cheap if a person could buy it for millions.
