Among the characteristics of the Fasiq: He breaks the covenant of Allah U after he has pledged to keep it. The one who breaks the covenant of Allah U will also break the covenant of human beings nonchalantly.

The covenant of Allah U is the fitrah or the innate belief and the observance of Islam. This belief has existed in human beings since they existed in the spiritual world, as Allah U tells us:

﴾وَإِذْ أَخَذَ رَبُّكَ مِنْ بَنِي آدَمَ مِنْ ظُهُورِهِمْ ذُرِّيَّتَهُمْ وَأَشْهَدَهُمْ عَلَى أَنفُسِهِمْ أَلَسْتُ بِرَبِّكُمْ قَالُوا بَلَى شَهِدْنَا﴿

“And [mention] when your Lord took from the children of Adam – from their loins – their descendants and made them testify of themselves, [saying to them], “Am I not your Lord?” They said, “Yes, we have testified.””

 [Surah Al-A’raaf: 172].

This covenant was taken naturally, thus, the nature of human beings is to have belief in Allah U, as Allah U says:

﴾فِطْرَةَ اللَّهِ الَّتِي فَطَرَ النَّاسَ عَلَيْهَا لا تَبْدِيلَ لِخَلْقِ اللَّهِ ذَلِكَ الدِّينُ الْقَيِّمُ﴿

“[Adhere to] the fitrah of Allah upon which He has created [all] people. No change should there be in the creation of Allah. That is the correct religion” [Surah Ar-Ruum: 30].
