People have to live with religion. The most perfect, true and chosen one religion is Islam. We, as a Muslim, have to make that our basic principle. As stated in Al-Qur’an:
This day have I perfected your religion for you, completed My favour upon you, and have chosen for you Islam as your religion. [Qur'an 5:3]
Surely the (true) religion with Allah is Islam [Qur'an 3:19]
Everything is arranged in Islam, including personal life, family, social life, politics, culture, ibadah, ‘aqidah, until things that most people ignore like ablution. All of that mentioned is arranged perfectly in Islam.
What did I mean with Islam, here is the true Islam, Islam that based on Al- Qur’an and As-Sunnah and understand them like the understanding of the Salafush Shalih (the old shalih (righteous) people, which means the Sahabah (companions) of Prophet Muhammad SAW).
Why do we have to follow the Salafush Shalih understanding of the Al-Qur’an and As-Sunnah? Because they are people who get the explanation of Al-Qur’an and As-Sunnah directly from Rasulullah SAW and they are the best generation of ummah. As stated in As-Sunnah:
Narrated Imran bin Husain:
“Allah’s Apostle said, ‘The best of my followers are those living in my generation (i.e. my contemporaries). and then those who will follow the latter” ‘Imran added, “I do not remember whether he mentioned two or three generations after his generation, then the Prophet added, ‘There will come after you, people who will bear witness without being asked to do so, and will be treacherous and untrustworthy, and they will vow and never fulfill their vows, and fatness will appear among them.” [Al-Bukhari and Muslim]
It’s so fool of us, if we want to want to understand Al-Qur’an and As-Sunnah without first following the sahabah way of understand it.
Actually, every need of a muslim is fulfilled by the shariah of Islam. Thus, a muslim, don’t have to seek any solution of any problem outside the rule of Islam.
With Rasulullah (May peace be upon him) passed away, it means that Islam has been perfected as a guidance of every human life. Tere is no need to add another guidance in this life outside Islam, for any Muslim.
