They -asws built for Al-Islam its foundations...

فِيهَا كَفْيُ الْمُكَتَفِي، وَ شِفَاءُ الْمُشْتَفِي‏، يَحْمَوْنَ حَمَاهُ، وَ يَرْعَوْنَ مَرْعَاهُ، وَ يَصُونُونَ مَصُونَهُ، وَ يُفَجِّرُونَ عُيُونَهُ، بِحُبِّ اللَّهِ وَ بِرِّهِ وَ تَعْظِيمِ أَمْرِهِ وَ ذِكْرِهِ بِمَا يُحِبُّ أَنْ يُذْكَرَ بِهِ، يَتَوَاصَلُونَ بِالْوِلَايَةِ، وَ يَتَنَازَعُونَ بِحُسْنِ الرِّعَايَةِ، In it is sufficient for the ones seeking sufficiency, and healing for the seekers of treatment, and protection for ones seeking protection, and care for ones seeking its care, and its protection safeguarding it, and its springs are bursting forth by the Love of Allah -azwj and His -azwj Kindness, and Reverence of His -azwj Commands and His -azwj Mention with what He -azwj Loves to be Mentioned with, connected with the Wilayah, and disputes with goodly care.

وَ يَتَسَاقَوْنَ‏ بِكَأْسٍ رَوِيَّةٍ، وَ يَتَلَاقَوْنَ بِحُسْنِ التَّحِيَّةِ، وَ أَخْلَاقٍ سَنِيَّةٍ، قُوَّامٌ عُلَمَاءُ أُمَنَاءُ، لَا يَسُوقُ‏ فِيهِمُ الرِّيبَةُ، وَ لَا تَشْرَعُ‏ فِيهِمُ الْغِيبَةُ، فَمَنِ اسْتَبْطَنَ مِنْ ذَلِكَ شَيْئاً اسْتَبْطَنَ خُلْقاً سَنِيّاً، And they are getting together with a saturating cup, and meeting with beautiful welcome, and high morals, stewardship of trustworthy scholars, there being no mistrust among them, nor does the backbiting start among them.

The one who hides something from that would be hiding morals. فَطُوبَى لِذِي قَلْبٍ سَلِيمٍ أَطَاعَ مَنْ يَهْدِيهِ، وَ اجْتَنَبَ مَنْ يُرْدِيهِ، وَ يَدْخُلُ مَدْخَلَ كَرَامَةٍ، وَ يَنَالُ سَبِيلَ سَلَامَةٍ، تَبْصِرَةً لِمَنْ بَصَّرَهُ، وَ طَاعَةً لِمَنْ يَهْدِيهِ‏ إِلَى أَفْضَلِ الدَّلَالَةِ، وَ كَشْفَاً لِغَطَاءِ الْجَهَالَةِ الْمُضِلَّةِ الْمُهْلِكَةِ، Beatitude is for the one with a tranquil heart, obeying the one -asws guiding him, and shunning the one who deviates him, and entering a prestigious entrance, and attaining the way of safety, being an insight for the one with insight, and obedience for the one guided to the superior evidence, and removal of the covering of ignorance, the straying, the destructive spree.
