Ibn Qayyim on Akhlaq: Entire religion is good character, manners

Ibn al-Qayyim, may Allah have mercy on him, said, “The religion itself is entirely good character, so whoever surpasses you in character has surpassed you in religion. Likewise, it is such with spirituality (al-tasawwuf). Al-Kanani said: Spirituality is itself good character, so whoever surpasses you in character has surpassed you in spirituality.”

And he said, “Good manners itself is the religion in its entirety.”

قال ابن القيم رحمه الله الدِّينُ كُلُّهُ خُلُقٌ فَمَنْ زَادَ عَلَيْكَ فِي الْخُلُقِ زَادَ عَلَيْكَ فِي الدِّينِ وَكَذَلِكَ التَّصَوُّفُ قَالَ الْكِنَانِيُّ التَّصَوُّفُ هُوَ الْخُلُقُ فَمَنْ زَادَ عَلَيْكَ فِي الْخُلُقِ فَقَدْ زَادَ عَلَيْكَ فِي التَّصَوُّفِ

وقال وَالْأَدَبُ هُوَ الدِّينُ كُلُّهُ
