In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Usaamah [may Allaah be pleased with him] narrated, “Once the Prophet [peace and blessings of Allaah be upon him] climbed a castle amongst the castles of Medina and said, “Do you see what I see? (No doubt) I see the spots where trials (temptations) will take place among your houses (and they will be) as numerous as the spots where raindrops fall.” [Saheeh Muslim 1878]
Al-Allaamah Saaleh Al-Fawzaan [may Allaah protect him] said:
The Prophet [peace and blessings of Allaah be upon him] has miracles (that cannot be equal to the miracles of anyone else) and from them is this miracle (mentioned in the hadeeth).
“The Prophet [peace and blessings of Allaah be upon him] stood at the top of a (look our from a) caste” -Meaning, on a high castle at one of the high towers of Madinah. There used to be high structures in Madinah and they were strong towers from which they watched the enemy. They climbed on them and were raised high whilst watching the enemy who was approaching them.
He climbed on one of them and said, “Do you see what I see?” They said, “No”. They cannot see what Allaah’s Messenger sees, because that was one of his specific qualities and miracles (which none was given besides him). This (i.e. when he asked them whether they can see what he can see was stated as a) warning to the Ummah. He said, “I see the spots where trials (temptations) will take place among your houses” – Meaning, within or close to your houses, because trials will overwhelm people in their houses. This is a warning from him that there will be trials that will reach the people.
What usually happens is that when people stay in their homes, they are safe from trials (temptations); but when they exit them and are exposed to temptation, they are afflicted; however the houses cannot protect one from these trials (temptations mentioned in this hadeeth). They will reach the people in their houses whilst they are dwelling in them. This – and Allaah knows best – will take place during the end of time when mass media, space broadcasts and satellites are developed – as they say – because indeed evil is transmitted with it easily and reaches the houses by means of screens and equipment that transmit events. The person views it in his home – as if he is there (i.e. where those events are taking place)- whilst it is at the furthest corner of earth.
The Messenger [peace and blessings of Allaah be upon him] never speaks out of his own desire and this is something that will (definitely) occur. The trials (temptations) will overwhelm the houses and enter them. This is a warning, news (based on divine revelation) from him [peace and blessings of Allaah be upon him]- warning the people when these widespread occur that a person should be cautious and protects his house from these trials (temptations). This (i.e. protecting oneself from these trials) will be accompanied with difficulty, but with patience and hoping for reward (in the afterlife), Allaah will aid him. (1)
