How true is this, we all know! It is explained in Quran and Ahadees that no one, literally no one can find peace without understanding the importance of Islam in his/her life. We all want contentment no matter from where we belong and how rich or poor we are. Allah Almighty has given control of each organ of body to man except heart and kept its satisfaction to himself and stated,Verily, in the remebrance of Allah do the hearts find peace. A person needs to relish the feel of home in every stage of life and this can only be felt in going down in sajda. The delight-fullness can't be expressed in words. May we find this peace within ourselves.
Don't leave any of your prayer and not forget to pray for all humankind! :)
