It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Every honorable speech or action that is not begun with the remembrance of Allah is incomplete and deficient.

It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: The servant has not done any deed that saves him more from Allah's punishment than the remembrance of Allah. Furthermore, Sayyiduna Mu'adh (may Allah be pleased with him) states that the Messenger of Allah (peace and blessings be upon him) said: Shall I not inform you of such a deed which is the best, the purest in the sight of your Lord, the one that raises your ranks the most, better for you than giving gold and silver in charity, and better for you than meeting your enemies so that you strike their necks and they strike your necks? The Companions said: Why not, O Messenger of Allah! Do tell us. He (peace and blessings be upon him) said: That deed is the remembrance of Allah Almighty.

It is narrated from Sayyiduna Abu Darda (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Shall I not tell you of the deed which is the best of all deeds ...? Then he mentioned a hadith similar to the one mentioned above.

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: In addition to the angels who record people’s deeds, there are other angels who roam the earth in search of the people of remembrance (dhikr). When they find a group engaged in remembrance, they call out to one another in a loud voice:“Come to your objective!”So they come and surround them up to the lowest heaven. (When these angels return,) Allah Almighty asks:“When you left My servants, what were they doing?”They say:“When we left them, they were praising You, declaring Your greatness, and remembering You.”(For ease, the conversation between Allah Almighty and the angels is presented in dialogue form):

Allah Almighty:“Have they seen Me?”
Angels:“No.”
Allah Almighty:“If they were to see Me, (how would they behave)?”
Angels:“If they were to see You, they would be even more intense and steadfast in praising, glorifying, and remembering You.”
Allah Almighty:“What is it that they are seeking?”
Angels:“They are asking for Paradise.”
Allah Almighty:“Have they seen Paradise?”
Angels:“No.”
Allah Almighty:“If they were to see Paradise, then?”
Angels:“If they were to see Paradise, their eagerness and desire for it would increase.”
Allah Almighty:“From what are they seeking refuge?”
Angels:“From the Fire.”
Allah Almighty:“Have they seen the Fire?”
Angels:“No.”
Allah Almighty:“If they were to see the Fire, then?”
Angels:“If they were to see it, they would flee from it even more intensely and would fear it even more.”
Allah Almighty:“(O angels!) I make you witnesses that I have forgiven them.”
Angels:“Among them is such-and-such a person who is a great sinner; he only came for some need, his intention was not to sit with them (so how was he forgiven)?”
Allah Almighty:“They are such a people that even their companion does not remain deprived.”

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Allah Almighty says: O son of Adam! If you remember Me within yourself, I will remember you within Myself; if you remember Me in an assembly, I will remember you in an assembly better than yours; if you draw near to Me by a span, I will draw near to you by a cubit; if you draw near to Me by a cubit, I will draw near to you by the span of two outstretched arms; and if you come to Me walking, I will come to you running. Imam Qatadah said: Thus, Allah Almighty is quicker in granting forgiveness.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Verily, Allah the Exalted says: When My servant remembers Me, I am with him. My servant thinks of Me as he expects of Me, and I treat him accordingly. I am with him when he remembers Me; if he remembers Me within himself, I also remember him within Myself.

It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) used to remember Allah Almighty at all times.

It is narrated from Abu Muslim Aghar, who says: I bear witness over Sayyiduna Abu Hurairah and Sayyiduna Abu Sa'id (may Allah be pleased with them both) that they bore witness over the Messenger of Allah (peace and blessings be upon him) that he said: When people sit together to remember Allah, the angels surround them, tranquility descends upon them, mercy covers them, and Allah mentions them before those who are with Him.

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: When people gather in one of the houses of Allah and recite the Book of Allah and teach it to one another, tranquility descends upon them, mercy covers them, the angels surround them, and Allah mentions them to those who are with Him. And whoever is held back by his deeds, his lineage will not bring him forward.

Narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him), he says: I said, "O Messenger of Allah! Which servants will have the highest rank with Allah Almighty on the Day of Resurrection?" He (peace and blessings be upon him) said: "Those who remember Allah Almighty abundantly." I said, "O Messenger of Allah! Who is the one who strives in the way of Allah?" He (peace and blessings be upon him) said: "If he strikes the disbelievers and polytheists with his sword until it breaks and becomes drenched in blood, even then, the one who remembers Allah Almighty will have a rank higher than him."
