When a Muslim is faced with a choice of being courteous to others and at the same time preserve his or her total dedication towards worship of True God Almighty, Allahu Ta'ala, he or she needs to be very, very firm about his or her Aqeedah @ Bedrock of Faith!
It's one thing to be respectful of others and allow them to worship whatever else they want or wish to but it is absolutely unbecoming for a Muslim to acknowledge anything else worthy of respect, devotion and to be in awe of except to Allah Subhanahu Wa Ta'ala!
You better get it right. Yes, if you are a Muslim, you can never divert to acknowledging, showing any sense of fear to or be in awe of any other thing or being except be in total devotion to Allah, Lord and Creator of all the worlds and each and every being, big and small, visible and invincible, microscopic and gargantuan, in this earthly realm and in the hidden spiritual worlds.
Being courteous and considerate to other's 'rights' to believe in anything else than God Almighty is a social characteristic of living in a multi faith, multi ethnic society such as Malaysia but it is of the utmost importance for a Muslim, male and female to stop short of going along with the Non Muslim's wish for us to acknowledge the validity of their object of faith.
If a Muslim, under any circumstances, goes ahead and accepts that there is another being or creation worthy of worship alongside Allah Subhanahu Wa Ta'ala, then he or she is deemed to have committed Syirik and is guilty of ascribing partners to Allah Rabbul Jaleel.
So, no matter that the Kaffir's rant and rave against our being adamant in Not acknowledging anything else to be worthy of worship save for Allahu Ta'ala, stay steadfast and committed to your Aqeedah and Iman towards Allahu Akbar, Malikul Kuddus, Rabbur Raheem!
Non Muslims must know that under no circumstances will a Muslim worth his name be a willing partner to worshipping any other thing on Earth or any other plane of existence, anything else but Almighty God, Most Compassionate, Most Merciful.
Do not expect Muslims who are true to their faith and Aqeedah to join you in worshipping some other thing except Allah, God Most High.
As for those Muslims who aren't sure about their faith, the best thing to do would be to improve your knowledge and ilm about Islam and do not give way to your Ego to cloud your judgement.
At the end of the day, it is Almighty God, Allah Subhanahu Wa Ta'ala Himself who would judge and determine as to whether one is a Mukmin or a Munafik or Fasik! No other humanbeing will be accountable to our own sins.
Let them call us as this and that, it doesn't change the fact that they are the dhalimoons and those whom Allah SWT will give due account for their actions against us! It is insignificant to us!
The Syafa'at of Rasulullah Sallalahu Alaihi Wassallam will be there for those who protect and preserve the dignity of Islam, Ad Deen ul Haqq sincerely for the sake of Allahu Ta'ala!
Ya aiyuhal Mukminoon, know that Allah Subhanahu Wa Ta'ala knows what's in our hearts and in our minds. Ensure that we do not go astray in our Aqeedah come what may, Insya Allah!
