Don't be deceived by the call to "good manners" only

بـسـم الله والحـمـد لله والـصلاة والـسـلام عــلى رسـول الله، وبـعـد

Allaah تعالى said:

﴿قَدْ نَعْلَمُ إِنَّهُ لَيَحْزُنُكَ الَّذِي يَقُولُونَ ۖ فَإِنَّهُمْ لَا يُكَذِّبُونَكَ وَلَـٰكِنَّ الظَّالِمِينَ بِآيَاتِ اللَّـهِ يَجْحَدُونَ﴾

{We know indeed the grief which their words cause you (O Muhammad); IT IS NOT YOU THAT THEY DENY, but it is the Verses (the Qur'aan) of Allaah that the Dhaalimoon (polytheists and wrong-doers) deny.} [Surah al-An`aam (6): 33]

The Prophet صلى الله عليه وسلم was called al-Ameen (the honest one) by the Muskriks even before he received any revelation and they still used to call him al-Ameen even after they had rejected his call. They never had the problem with the personality.

So, the first and foremost thing we have to understand is that the Mushriks never stopped the Prophet صلى الله عليه وسلم from calling towards good manners, or doing good to the neighbors, or feeding the poor and taking care of the widows and orphans; but it was the `Aqeedah and the call to Tawheed that they were against.

﴿أَجَعَلَ الْآلِهَةَ إِلَـٰهًا وَاحِدًا ۖ إِنَّ هَـٰذَا لَشَيْءٌ عُجَابٌ﴾

{“Has he (Muhmmad) made (all) the gods all into One God. Verily, this is a curious thing!”} [Surah Saad (38):5]

So don’t be amazed by the good manners of the Sufees, the Rawaafidh, the Mu`tazilah, or the Kuffaar, because this is how Shaitaan wants to deceive us. Always remember teaching/learning `Aqeedah comes first. Do not be content with learning good manners with the creation as the primary subject while `Aqeedah is given a secondary preference.
