Muslims must never forget that Satan is always working to cause enmity between Muslims in order to prevent their unity and solidarity. Our Lord warns believers of this danger:
Say to My servants that they should only say the best. Satan wants to stir up trouble between them. Satan is an outright enemy to man. (Surat al-Isra’, 53)
This verse advises Muslims to avoid directing hurtful, mocking, harsh, and accusing words against other Muslims and points out the need for decent conduct in the pursuit of unity.
The Qur'an also points out that such disputes and other damaging behavior impair one's sense of belonging and weaken the Muslims' power. Our Lord says:
Obey Allah and His Messenger and do not quarrel among yourselves, lest you lose heart and your momentum disappear. And be steadfast. Allah is with the steadfast. (Surat al-Anfal, 46)
If the Islamic world wants to erect a powerful, stable, and prosperous civilization that guides and illuminates the world in every aspect, it must act in union. The lack of such a union is responsible for the Islamic world's discord and separation, the absence of a common voice, and the defenselessness of innocent Muslims. Countless poor women, children, and elderly people are desperately in need of rescue from oppression in Palestine, Kashmir, East Turkistan (home of the Chinese-ruled Muslim Uighur people), the southern Philippines (home of the Muslim Moro people) and many other regions. The responsibility for these people belongs to the Islamic world before anyone else. Muslims must never forget the Prophet's (may Allah bless him and grant him peace) following words:
A Muslim is a Muslim's brother. He does not wrong him or abandon him. (Sahih Bukhari and Sahih Muslim)The Islamic world must put its various disputes aside and remember that all Muslims are "brothers" and "sisters" so that it can provide role models who reflect the true character of Islam and its ideals. This unity of the believers is a gift and grace of Allah. Sincere Muslims must thank our Lord for these benefits and obey His command "not to separate":
Hold fast to the rope of Allah all together, and do not separate. Remember Allah's blessing to you when you were enemies, and He joined your hearts together so that you became brothers by His blessing. You were on the very brink of a pit of the Fire, and He rescued you from it. In this way Allah makes His Signs clear to you, so that hopefully you will be guided. (Surah Al ‘Imran, 103)
