The basis of reformation of the heart is occupying it with the remembrance of Allah. 13ـ أصْلُ صَلاحِ القَلْبِ اِشْتِغالُهُ بِذِكْرِ اللّهِ. Verily Allah, the Glorified, has made [His] remembrance a polishing for the hearts, to see with after blindness and listen with after deafness and to become submissive with it after obduracy. 14ـ إنَّ اللّهَ سُبْحانَهُ جَعَلَ الذِّكْرَ جَلاءَ القُلُوبِ، تَبْصُرُ بِِهِ بَعْدَ العِشْوَةِ، وتَسْمَعُ بِهِ بَعْدَ الوَقْرَةِ، وتَنْقادُ بِهِ بَعْدَ المُعانَدَةِ.

Verily there are those who hold on to the remembrance of Allah and have taken it in lieu of this world and thus neither trade nor business has preoccupied them from [His] remembrance. They spend the days of their lives with it and shout it in the ears of the negligent [in order to remind them]. 15ـ إنَّ لِلذِّكْرِ أهْلاً أخَذُوهُ مِنَ الدُّنيا بَدَلاً، فَلَمْ تَشْغَلْهُمْ تِجارَةٌ ولا بَيْعٌ عَنْ ذِكْر، يَقْطَعُونَ بِهِ أيّامَ الحَياةِ،وَ يَهْتِفُونَ بِهِ في آذانِ الغافِلينَ.

Remembrance is being in the company of the beloved. 16ـ اَلذِّكْرُ مُجالَسَةُ المَحْبُوبِ. Remembering [Allah] is the key to intimacy [and nearness with Him]. 17ـ اَلذِّكْرُ مِفْتاحُ الأُنسِ. The remembrance [of Allah] is a light and guidance. 18ـ اَلذِّكْرُ نُورٌ، ورُشْدٌ. The remembrance [of Allah] is the delight of the lovers. 19ـ اَلذِّكْرُ لَذَّةُ المُحِبِّينَ. Remembrance of Allah brings comfort [and delight]. 20ـ اَلذِّكرُ يَشْرَحُ الصَّدرَ.

Remembrance of Allah is the polishing of visions and illumination of the inner selves. 21ـ اَلذِّكرُ جَلاءُ البَصائِرِ ونُورُ السَّرائرِ. Remembrance [of Allah] is the guidance of the intellects and the enlightenment of the souls. 22ـ اَلذِّكْرُ هِدايَةُ العُقُولِ، وتَبْصِرَةُ النُّفُوسِ. When you see that Allah is making you comfortable with His remembrance, then [know that] He loves you. 23ـ إذا رَأيْتَ اللّهَ يُؤْنِسُكَ بِذِكْرِهِ فَقَدْ أحَبَّكَ.

When you see that Allah is making you comfortable with His creation and isolating you from His remembrance, then (know that) He dislikes you. 24ـ إذا رَأيْتَ اللّهَ يُؤْنِسُكَ بِخَلْقِهِ، ويُوحِشُكَ مِنْ ذِكْرِهِ فَقَدْ أبْغَضَكَ. It is through the remembrance of Allah that mercy descends. 25ـ بِذِكْرِ اللّهِ تُسْتَنْزَلُ الرَّحمَةُ. Through the constant remembrance of Allah, heedlessness is dispelled. 26ـ بِدَاومِ ذِكْرِ اللّهِ تَنْجابُ الغَفْلَةُ.

The fruit of remembrance [of Allah] is illumination of the hearts. 27ـ ثَمَرَةُ الذِّكْرِ اِسْتِنارَةُ القُلُوبِ.
