habit very much. There is no doubt in the fact that Satan is an eternal enemy of mankind, as Allah عَزَّوَجَلَّ mentions in the Holy Quran:

اِنَّ الشَّیْطٰنَ یَنْزَغُ بَیْنَهُمْؕ-اِنَّ الشَّیْطٰنَ كَانَ لِلْاِنْسَانِ عَدُوًّا مُّبِیْنًا(۵۳)

Undoubtedly Shaytan causes mischief amongst them;
 indeed Shaytan is an open enemy of human beings.

[Kanz-ul-Iman (Translation of Quran)] (Part 15, Surah Bani Israel, Ayah no. 53)

صَلُّوۡا عَلَى الۡحَبِيۡب                 صَلَّى اللّٰهُ عَلٰى مُحَمَّد

Satan will definitely not bear the fact that Muslims:

٭   Remain united with one another

٭   Be well-wishers of one another

٭   Safeguard each other’s honour

٭   Overlook the mistakes of one another

٭   Forgive one another

٭   Forgive one’s own rights

٭   Take care of the rights of one another

٭   Help each other

Rather, Satan will wish that Muslims:

٭   Fight and quarrel a lot with one another

٭   Tarnish the honour of one another

٭   Indulge in immorality and indecent talks

٭   Swear a lot at one another

٭   Slap a person twice in revenge when she has been slapped once
