Prophets Creation And Spiritual Status
sallAllahu alaihi wassallam - peace & blessings be upon him
Quran commands the believers to send salawaat on Prophet Muhammad ﷺ. Salawaat in Arabic means 'prayers, blessings, greetings, mercy', also called durood. The salawaat are included in our daily obligatory prayers (fives times salah). Additionally, Muslims are encouraged to send salawaat even when outside of obligatory prayers, throughout the day out of love and respect and by doing so we form a spiritual connection with him. The Quran says very clearly to send blessings upon Prophet Muhammad ﷺ and in fact it is says that Allah ﷻ and His Angels also send upon him every day: “Allah sends His Salat (Graces, Honours, Blessings, Mercy, etc.) on the Prophet (Muhammad) and also His angels too (ask Allah to bless him). O you who believe! Send your Salat on (ask Allah to bless) him (Muhammad), and (you should) greet (salute) him with the Islamic way of greeting (salutation i.e. Asaalamu 'Alaikum).” There’s a hadith that teaches us the three important lessons and one of them is sending salawaat (peace and blessings) upon Prophet Muhammad ﷺ. It’s narrated that the Prophet ﷺ climbed up on the minbar (pulpit), and then said three times “ameen (amen), ameen, ameen.” It was said, "O Messenger of Allah, why did you say ameen'' He said “Jibril (Gabriel) came to me and said, "O Muhammad, he is doomed who hears you (your name) mentioned and does not say salla (blessings, mercy) upon you.'' He said, "Say Ameen,'' so I said “Ameen”. Then he said, "He is doomed who sees the month of Ramadan come and go, and he has not been forgiven.'' He said, "Say Ameen,'' so I said “Ameen”. Then he said, "He is doomed who grows up and both his parents or one of them are still alive, and they do not cause him to enter Paradise.'' He said, "Say Ameen,'' so I said “Ameen”. By him saying ‘ameen (amen)’ - an utterance in the form of request for acceptance after making supplications to Allah ﷻ - proves that these three conditions have been made effective till the Day of Judgment. Therefore saying "sallAllahu alaihi wassallam (peace & blessings be upon him)" whenever Prophet's name is mentioned is as important as forgiveness in Ramadaan and serving one’s parents, two major sources of earning Allah’s mercy, which whoever remains deprived of is truly deprived and unfortunate.
The salawaat i.e. peace and blessings, that we say when Prophet's name is mentioned, is a source of mercy for believers in this world and the hereafter and that’s due to many factors. Firstly that he will intercede for major sins on the Day of Judgment. Secondly, those who do so will be close to him on judgment day and this will be due to the spiritual nearness gained through sending abundant blessings in this world. Thirdly, Allah ﷻ and His angels continually send blessings upon him as per Quran, therefore by us sending blessings upon him we tend to honor the most precious creation of Allah ﷻ and in return He honors us. Such honorable people are blessed, remaining content and at peace, in this world and the hereafter. The act helps us feel spiritually blessed and that is something no words can truly express, it can only be experienced especially by the peace our minds, hearts and soul experience. At this point it's also important to mention that if we were to simply call him by his name as we call each other, without required salawaat, may cause us to forget importance of his great status. This can also become a source of disrespect towards his personality, which may cause us to fall in to a punishable sin in the hereafter.
