Benefits and Issues:
The result of Satan's circulation within the human body manifests in the form of doubts, whisperings (waswasah), and disobedience to Allah Ta'ala. The only means of protection from his tribulations is, along with faith (iman) and righteous deeds (amal salih), to engage abundantly in the remembrance (dhikr) of Allah. Otherwise, it is very difficult to be safe from his attacks, and all of this is according to the decree (qadar) and will (mashiyyah) of Allah, the Mighty and Majestic.

Hadith Commentary: Benefits and Issues: The Messenger of Allah (sallallahu alayhi wa sallam), during the last ten days of Ramadan, was going to leave his wife at home when two Ansari men passed by him. They hastened their pace so that you would not feel any hesitation in conversing due to them, or, out of modesty and shyness, they quickly turned back. However, the Messenger of Allah (sallallahu alayhi wa sallam) considered that Satan circulates within a human being like blood, and perhaps he might cause some suspicion to arise in their hearts. Therefore, you said, "Walk calmly and with tranquility; this is my wife." In this way, you immediately removed any potential suspicion, because, according to Imam Shafi'i, having suspicion about you is disbelief (kufr). Therefore, the requirement of goodwill and compassion was that they be protected from this. Having suspicion about other people is not disbelief, but it is certainly sinful, and in this way, dislike and hatred can arise in a person's heart regarding someone, and this can also lead to slander and backbiting. Therefore, one should not give anyone an opportunity for suspicion, nor should one do anything that gives rise to ill thoughts. And if such a situation ever arises, one should inform others of the reality of the matter, so that suspicion does not arise in their hearts and they do not become sinful. In this narration, mention is made of one man, although there were two; so here "rajul" (man) is for the genus, meaning the passersby were men—the specification of one or two is not intended. Or, one was a little behind the other; when the first was addressed, the second also caught up.
