"And hold firmly to the rope (His covenant or the Qur'an) of Allah all together and do not become divided." (3:103)
Allah (SWT) makes it clear in the Qur'an that unity of the Muslim Ummah is very important. He tells us not to be divided and to hold tightly to the teachings of the Qur'an. Unfortunately we Muslims have divided ourselves into different sects. We bicker over trite issues that hold no meaning and do not benefit the Ummah in any way. Muslims have forgotten what Allah says in the Qur'an about unity and its importance.
Today, if the Muslims look at themselves they will see a group of people separated from one another. The Prophet Muhammad (PBUH) said, "Believers are like the parts of a building, each one supporting the other." (Sahih Al-Bukhari)
How can we support each other if we are not united? How can we love each other like brothers and sisters in Islam if we hold misconceptions about each other in our hearts?
The answer is simple: We, as the Muslim Ummah, have to overcome the minor and irrelevant differences that separate us. If we are able to do that we will notice that all Muslims believe in the same things: Tauheed (the oneness of Allah), all the Prophets (peace be upon them all), all the holy Books, all of Allah's angels and the day of judgement. Not to mention that every Muslim tries to follow the Qur'an and Sunnah.
Muslims should understand that unity is what will make us move forward in this world. Today the Muslim Ummah is behind in everything. Education, technology, trade and, most importantly, our faith. Non-muslims may not believe in our faith but their unity has made them come very far. Remember the era when the Muslims were united and held on to Allah's rope tightly? The Islamic empire spread from the east to west and Allah blessed them with wealth, fame, victory and honor. Muslims need to be united now more than ever. We have to think about what we will and we can do to make our lives in this world and the hereafter better and blessed.
