God says, “Who so seeketh as religion (Al-Din) other than the surrender (to Allah), It will not be accepted from him” {3:85}.Here Allah says acknowledged and accepted way of life is Al-Islam. Here the word Al-din widens its range. In other words we can say that Allah (SWT) demands us to follow Al-Islam in its Holistic sense (i.e.) Al-Din .Al-Din has been defined in al.Mu’jam al Wasit as
According to Al-Wasit, Al-Din encompasses not only verbal confession and belief (according to confession) but it encompasses all the below captioned areas of human life:
Al-Sirah (conduct,attitude, behavior, way of life)
Al-‘Aadah (habit ,customs)
Al-Hal(condition ,state) 
A- War’a( piousness, godliness)
Al-Muluk(supreme,authority,sovereignty)
Al-Qazu’ (canonical law)
Al- Hukum (the Absolute authoritarian)
Al –Tadbir (the planning,the politics) as well.
When we take al-Din in this Holistic manner, consequently the habits, customs, conduct and behavior etc .come under the jurisdiction of al-Islam. So Islam from its very root salama (سلم) dose not only stands for way of life; world view, ideology, and culture and civilization too. It is why that alternatives and specialties should be in complete conformity with Islamic law. So the customs and rituals having no support of Quran, Hadith Sunnah and ‘Amal of Suhabah does not in any way constitute Islamic Culture .Mohammad Marmaduke Pikhtal says in his book, Cultural side of Islam that Islamic culture does not mean the culture which the Muslims have ever achieved from external sources, but it meant that culture which has a firm base on Islamic principles and the goal of which is to lead the humans towards eternal success and joy.
