The Effects of Worship on a Muslims Life by Shaykh Abdul Muhsin al-Abbad
Worship requires two conditions in order to be accepted, firstly sincerity to Allah, and secondly adhering to the practice of the Prophet (SAW). Being sincere to Allah is a must, whereby a person should not associate partners with Allah. One does not observe any kind of worship to anything except Allah and one should follow the example of the Prophet (SAW). One does not worship Allah; unless they practice what the prophet established (SAW).
