Ibn Mas'ud reported Allah's Messenger ﷺ as saying, “Allah brighten a man who hears what I say, gets it by heart, retains it, and passes it on to others! Many a bearer of knowledge is not versed in it, and many a bearer of knowledge conveys it to one who is more versed than he is. There are three things on account of which no rancour enters a Muslim's heart

Abu Sa'id said Allah's Messenger ﷺ was asked who would be most excellent and most exalted in degree in Allah’s estimation on the day of resurrection, and replied, “The men and women who make frequent mention of Allah.” He was asked if they would be superior even to the man who had fought in Allah’s path, and replied, “Even though he plied his sword among infidels and polytheists till it was broken and smeared with blood, the one who made mention of Allah would have a more excellent degree than he.” Ahmad and Tirmidhi transmitted it, the latter saying this is a gharib tradition.

Ibn ‘Abbas reported Allah's Messenger ﷺ as saying, “The devil is couching at the heart of the son of Adam. When he mentions Allah he withdraws, but when he is neglectful he makes evil suggestions.” Bukhari mentioned it in a note.

Malik said he heard Allah's Messenger ﷺ used to say, “The one who makes mention of Allah among those who are negligent is like one who goes on fighting after others have fled; the one who makes mention of Allah among those who are negligent is like a green branch upon a withered tree; (A version has, “Like a green tree amidst the trees”); the one who makes mention of Allah among those who are negligent is like a lamp in a dark house; the one who makes mention of Allah among those who are negligent will be shown by Allah during his lifetime his resting-place in paradise; and the one who makes mention of Allah among those who are negligent will be forgiven as many sins as the number of those who have the faculty of speech (fasih) and those who are destitute of it (a'jam)” Fasih refers to human beings and a'jam to animals. Razin transmitted it.

Mu'adh b. Jabal said, “A man does nothing more calculated to rescue him from Allah’s punishment than making mention of Allah.” Malik, Tirmidhi and Ibn Majah transmitted it.

Abu Huraira reported Allah's Messenger ﷺ as stating that Allah says, "I am with my servant when he remembers me and his lips move making mention of me." Bukhari transmitted it.

‘Abdallah b. ‘Umar told that the Prophet (ﷺ) used to say, “Everything has a polish, and the polish for hearts is rememberance of Allah. Nothing is more calculated to resuce from Allah’s punishment than remembrance of Allah.” He was asked whether this did not apply also to jihad in Allah’s path, and said, “Not even if one should ply his sword till it is broken.” Baihaqi transmitted it in [Kitab] ad-Da'awat al-kabir.

Abu Huraira reported Allah's Messenger ﷺ as saying, “Allah had ninety-nine names, one short of a hundered. He who retains them in his memory* will enter paradise.” A version has, “And He is One. He loves what is single.” *The Arabic is ahsaha, a word which has different meanings. Besides the meaning above can mean to number, to reach the last number, to understand, to attain comprehensive knowledge. (Bukhari and Muslim.)

Abu Huraira reported Allah's Messenger ﷺ as saying, “Allah Most High has ninety-nine names. He who retains them in his memory will enter paradise. He is Allah than whom there is no god, the Compassionate, the Merciful, the King, the Holy, the Source of Peace, the Preserver of security, the Protector, the Mighty, the Overpowering, the Great in Majesty, the Creator, the Maker, the Fashioner, the Forgiver, the Dominant, the Bestower, the Provider, the Decider, the Knower, the Withholder, the Plentiful Giver, the Abaser, the Exalter, the Honourer, the Humiliator, the Hearer, the Seer, the Judge, the Just, the Gracious, the Informed, the Clement, the Incomparably Great, the Forgiving, the Rewarder, the Most High, the Most Great, the Preserver, the Sustainer, the Reckoner, the Majestic, the Generous, the Watcher, the Answerer, the Liberal, the Wise, the Loving, the Glorious, the Raiser, the Witness, the Real, the Trustee, the Strong, the Firm, the Patron, the Praiseworthy, the All-Knowing, the Originator, the Restorer to life, the Giver of life, the Giver of death, the Living, the Eternal, the Self-sufficient, the Grand, the One, the Single, He to whom men repair, the Powerful, the Prevailing, the Advancer, the Delayer, the First, the Last, the Outward, the Inward, the Governor, the Sublime, the Amply Beneficent, the Accepter of Repentance, the Avenger, the Pardoner, the Kindly, the Ruler of the Kingdom, the Lord of Majesty and Splendour, the Equitable, the Gatherer, the Independent, the Enricher, the Depriver, the Harmer, the Benefiter, the Light, the Guide, the First Cause*, the Enduring, the Inheritor, the Director, the Patient.” *Or, 'the Incomparable' (al-badi'). Tirmidhi and Baihaqi, in [Kitab] ad-Da'awat al-kabir, transmitted it, Tirmidhi saying this a gharib tradition.

Buraida told that Allah's Messenger ﷺ heard a man saying, “O Allah I ask Thee by virtue of Thy being Allah than whom there is no god, the One, He to whom men repair, who has not begotten and has not been begotten, and to whom no one is equal,” and said, “He has supplicated Allah using His greatest name, when asked by which He gives and when supplicated by which He answers.” Tirmidhi and Abu Dawud transmitted it.
