All praises and adoration is due to Almighty Allah, the Lord of the world, the one who created all creatures in the extremely best way. I beseech the irrevocable blessings and benediction on the soul of the Noble Prophet (SAW).
No doubt that the one who is ascribed with the best of mannered of all creatures by his Lord is Prophet Muhammad (Saw). Allah says in the Quran " there has certainly been for you in the messenger of Allah an excellent pattern (manner) for anyone whose hope is in Allah and the last Day and (who) remembers Allah often (sura AlAhzab vs 21).
Also Allah says in another part of the Quran " And verily (indeed), you are of a great moral character (manner)" (Sura Ahzab vs 4)

Islam as a religion has laid prominence on all things for us starting from the way we live, behave, transact (by and sell), communicate, speak,relate (with people), nurture and so on. With these teachings and guidelines. Muslims nowadays still fall trapped due to the hand of lightheadedness they show towards on of the most important thing a Muslim must have which is 'manner'.
This manner has led to the destruction,tears, crises, vices, broken homes, construction, happiness,joy, understanding, bonding, success, victory where there is presence of it.
