There is a Difference between a Believer and a Muslim

Allah chastises the bedouins who, when they embraced Islam, claimed for themselves the grade of faithful believers. However, Faith had not yet firmly entered their hearts,

قَالَتِ الاٌّعْرَابُ ءَامَنَّا قُل لَّمْ تُؤْمِنُواْ وَلَـكِن قُولُواْ أَسْلَمْنَا وَلَمَّا يَدْخُلِ الايمَـنُ فِى قُلُوبِكُمْ

Sequence of Verses in the Surah

In the preceding verses of the Surah it was stated that the basis of honour in the sight of Allah is righteousness which is an inner quality, and Allah alone knows it. It is improper for any man to claim self-sanctification. In the current set of verses, it is stated, on account of a particular incident, that the real basis of faith is the inner acceptance of the heart. Mere lip-service to faith does not count the person as a faithful believer. In the entire Surah, first the rights of the Prophet were set out and then the rules of how to respect and honour him. Next the individual and collective rights and rules of mannerism were set down to be applied in social life. Now at the conclusion of the Surah it is reiterated that in the Hereafter good deeds will be accepted and rewarded on the basis of faith, sincere belief of the heart and obedience to Allah and His Messenger ﷺ .
