The Soor (horn/trumpet)
The Messenger (sal Allahu alaihi wa sallam) said, “How can I relax when the bearer of the Soor (horn/trumpet) has put the Soor to his lips and tilted his forehead, listening and waiting for the command to blow it?” The Muslims asked, “O Messenger of Allah! What should we say?” He (sal Allahu alaihi wa sallam) said, “Say Hasbunallah wa ni’mal wakeel. Tawakkalnaa ‘alallahi Robbina (Allah is Sufficient for us and He is the best Disposer of affairs, we put our trust in Allah, our Lord).”
[At-Tirmidhi - Classed as Sahih by Sh al-Albaani]
It should be understood that the Soor, translated to be the horn or the trumpet used to signal the Day of Resurrection, is not as we picture or imagine it to be.
The Messenger (sal Allahu alaihi wa sallam) only explained it in terms of the words that we know. Its real concept and shape is part of the unseen and the knowledge of it lies only with Allah.
This hadith shows us the reality of how close the day of judgment is whereby the Messenger (sal Allahu alaihi wa sallam) mentioned that the angel who is appointed to blow the trumpet (his name is Israafeel as mentioned in the authentic ahadith) has placed the trumpet on his mouth and is waiting for Allah to give him the order to blow it in order for the resurrection to begin.
The Messenger (sal Allahu alaihi wa sallam) was so effected by this that he said “how can I relax” and the companions (radi Allahu anhum) were so effected that the Messenger (sal Allahu alaihi wa sallam) told them to say “Hasbiyallah wa ni’mal wakeel”.
One should ask themselves if the Messenger and His companions who are the greatest of people were effected like this, what have we done in order to be ready and prepared for such a day?
And Allah Knows Best!
