Surah 9. Al-Tawba
Ayah 90
90 وَجَآءَ ٱلْمُعَذِّرُونَ مِنَ ٱلْأَعْرَابِ لِيُؤْذَنَ لَهُمْ وَقَعَدَ ٱلَّذِينَ كَذَبُوا۟ ٱللَّهَ وَرَسُولَهُۥ ۚ سَيُصِيبُ ٱلَّذِينَ كَفَرُوا۟ مِنْهُمْ عَذَابٌ أَلِيمٌ
[90] And many from among the Bedouins90 also came with their excuses that they, too, might be allowed to remain behind: thus stayed behind those who had made a false compact of Faith with Allah and His Messenger. In the near future those from among the Bedouins who adopted the way of unbelief91 shall meet with a painful chastisement.
90Here the word "Bedouins" refers to those Arabs who lived in the desert near Al-Madinah.
91The hypocritical profession of Islam has been called the way of unbelief, because that profession of faith which lacks practical proof, surrender, sincerity and obedience, is, in fact, unbelief. As such persons prefer their own interests and worldly desires to Allah and His Way, they shall be dealt with by Allah as unbelievers and rebels, even if they could not be legally treated as such in this world but were considered Muslims due to their profession of faith. This is because in the life of this world, the Islamic Law treats as unbelievers only such hypocrites as are guilty of open unbelief, rebellion, treachery or infidelity. That is why there are many cases of hypocrisy that do not come under kufr in the Islamic Shari'ah. However, this does not mean that if one escaped the penalty according to the Islamic Code, one will escape punishment According to the Divine Judgment also.
