Islam Is Worship of the Creator

Islam has a distinct worldview (dīn), informed by the centrality and essentiality of Allah (the One God). This dīn of Islam is a way of life - a life transaction. The world 'religion' can be misleading because Islam comprehends all life. It elevates the intentions, words and actions of those who submit (al-muslimūn) to the Wish of Allah, the Real.

As to our purpose in this ephemeral life it is to strive for the pleasure of Allah (may His Majesty be exalted) in all what we do - by abiding to the revealed Law/ Shariah. Law/ Shariah.

 Living Islam: Following its authentic sources, the Quran & Sunnah for the maqāṣid (the purpose of the law): Shariah as a mercy and guidance for humanity, defending the five essentials of human well-being (religion, life, intellect, lineage, and property), representating moderate, mainstream Islam.

  Islamic tradition: Rediscovering and re-deploying the partially forgotten, sometimes lost–original and authentic Way of Prophet Muhammad ﷺ, confirmed and guarded by the scholars and saints of Islam for over 14 centuries up to today.

In the case of Islam, tradition describes furthermore the words, sayings, and actions reported from Prophet Muhammad may Allah bless him and grant him peace, which have been recorded in the hadith collections together with the entire Islamic religion, such as the Islamic schools of law, spirituality, sanctity, etc.
Imam Ahmad Vālsan, rh.
