Allah the all-mighty has said: "Therefore remember Me. I will remember you. Be grateful to Me and never show Me ingratitude."

And He said: "Oh you who believe, remember Allah time and again."

And He said: "And the men and women who remember Allah frequently, Allah has prepared for them forgiveness and a great reward."

And He said: "And remember your Lord by your tongue and within yourself, humbly and in awe, without loudness, by words in the morning and in the afternoon, and be not among who are neglectful."

The Prophet (S.A.W) said: "He who remembers his Lord and he who does not remember his Lord are like the living and the Dead."

And he said: "shall I not tell you about the best of your works, the purest of your possessions, your most elevated station, the thing that is better for you than spending your gold and silver [in the way of Allah], and better for you than meeting your enemies and slaying them and being slain?" "Oh yes," they said. He said, "Remembrance of almighty Allah."
And he said: "Almighty Allah says, 'I am with my slave when he think of me and I am with him when he mentions me. For if he mentions me to himself, I have mentioned him to myself; and if he mentions me in a gathering, I have mentioned him in a superior gathering. If he approaches me by a hand's width, I approaches him by an arm's length; and if he approaches me by an arm's length, I approach him by by a mile's length. And if he comes to me walking, I hasten to him swiftly."

Abdullah bin Busr said that a man asked the Prophet (S.A.W) "Oh Prophet, there are so many ways that we are permitted to worship Allah. Please give me a simple thing that I can do." The Prophet (P.B.O.H) said: "Let your tongue always be moist with the remembrance of Allah."

And he said: "Whoever reads one letter from the book of Allah, will receive one Hassana, and one[i] Hassana[/i] comes with ten like it. I do not say that Alif, Lam, Mim, is a letter. Indeed Alif is a letter, and Lam is a letter, and Mim is a letter."
'Uqbah bin 'Amir (R.T.A) said: "Whoever sits and does not mention the name of Allah [before he rises] will find it a cause of sorrow. Whoever lies down to sleep and does not mention the name of Allah before rising will find it a cause of sorrow."

And the Prophet (S.A.W) said: "Whoever sits in an assembly of people who do not mention the name of Allah in their gathering, and who do not ask Allah for His blessings on their Prophet, will find it a cause of sorrow. If he wishes He will punish them, and if He wishes he will forgive them."

And He said: "No people may rise from an assembly in which they have failed to mention the Name of Allah without it being as if they were getting off a dead donkey's rotting back, and it would be a cause of affliction for them."
