He Himself says: Hollowed be Allah from what they describe, except the servants of Allah freed (from sins) (37:159 160); they do not comprehend Him in knowledge (20:110).
For example, it has been narrated through various chains of narrators that: "Remembrance of Allah is good in all conditions." It has been narrated that the Messenger of Allah (s.a.w.a.) came up to his companions, and said: "Feast you in the meadows of the Garden." They said: "O Messenger of Allah! And what are the meadows of the Garden?" He said: "The gatherings of remembrance; go there in the mornings and in the evenings and remember (Allah).
And whoever likes to know (what is) his position near Allah, he should see what is the position of Allah near him (i.e., in his heart); because surely Allah gives a servant the same position which the servant gives to Allah vis-à-vis, his own self. And know that your best deeds (near your King) and the purest and the highest of them in ranks, and the best of all that the sun shines on, is the remembrance of (Allah).
the High, because Allah the High, has said concerning His Own Self: 'I am the companion of him who remembers Me'; and He, the High One, has said: 'Therefore remember Me; I will remember you with My bounty; you remember Me with obedience and worship, I will remember you with bounties, and beneficence, and comfort, and (My) pleasure.' " ('Uddatu 'd da'i) as Sadiq (a.s.) said: "Surely Allah, the Blessed, the High, says: 'Whoever is too preoccupied with My remembrance to be able to ask Me (for his needs), I give him the best of what I give to him who asks Me."'(al Mahasin; ad Da'awat, ar Rawandi) al Husayn al Bazzaz said: "Abu 'Abdillah (a.s.) told me: 'Should I not tell you the most difficult (thing) which Allah has made obligatory for His creatures?' I said: 'Yes, certainly.' He said: 'To do justice to the people (even) against yourself, and your beneficence to your brother, and remembrance of Allah in every place.
