Messenger of Allah(ﷺ) said: "There is no soul that died bearing witness to La ilaha illallah, and that I am the Messenger of Allah, from the heart with certainity, but Allah will forgive it."

"The Messenger of Allah(ﷺ) said: (About saying) La ilaha illah - no deed takes precedence over it and it does not leave any sin.'"

the Messenger of Allah(ﷺ) said: "Whoever says one hundered times each day: La ilaha illahu wahdahu la sharikalahu, wa lahul-mulku wa lahul hamduwa huwa ala kulli shayin qadeer (None has the right to be worshipped but Allah alone, with no partner or associate. His is the dominion, all praise is to Him, and He is able to do all things), it will be equivalent to him freeing ten slaves, and one hundered merits will be recorded for him, and one hundered bad deeds will be erased from (his record), and it will be a protection for him against Satan all day until night comes. No one can do anything better then him except one who says more.'"

the Prophet(ﷺ) said: "Whoever says, following the morning prayer: La ilaha illallahu wahdahu la sahrikalau, lahul mulku wa lahul hamdu, bi yadihil khair, wa huwa ala kulli shay'in qadir (None has the right to be worshipped but Allah alone, with no partner or associate. His is the dominion, all praise is to Him, in His Hand is all goodness, and He is Able to do all things), it will be as if he freed slave from among the sons of Isma'il."

"I heard the Messenger of Allah (ﷺ) say: 'The best of remembrance is La ilaha illallah (None has the right to be worshipped but Allah), and the best of supplication is Al-Hamdu Lillah (praise is to Allah).'"

the Messenger of Allah (ﷺ) told them: "One of the slaves of Allah said: 'Ya Rabb! Lakal-hamdu kama yanbagi li-jalali Wajhika wa li 'azima sultanika (O Lord, to You is praise as befits the Glory of Your Face and the greatness of Your Might.)' The angels were uncertain and did not know how to write this down, so they ascended to heaven and said: 'O our Lord, Your slave has said a word that we do not know how to write down.' Allah said - and He knows best what His slave said - 'What did My slave say?' They said: 'O Lord, he said "Ya Rabb! Lakal-hamdu kama yanbagi li-jalali Wajhika wa li'azima sultanika (O Lord, to You is praise as befits the Glory of Your Face and the greatness of your Might).'" Allah said to them: 'Write it down as My slave said it, until he meets Me and I shall reward him for it.'"

his father said: "I prayed with the Prophet (ﷺ) and a man said: 'Alhamdu lillahi hamdan kathiran tayyiban mubarakan fihi (Praise is to Allah, much, good and blessed praise).' When the Prophet (ﷺ) finished praying, he said: 'Who said that?' The man said: 'It was me, but I did not mean anything but good.' He said: 'The gates of heaven were opened because of it and nothing prevented it from reaching the Throne.'"

"When the Messenger of Allah (ﷺ) saw something he liked, he would say: 'Al-hamdu lillahil-ladhi bi ni'matihi tatimmus-salihat (Praise is to Allah by Whose grace good deeds are completed).' And if he saw something that he disliked, he would say: 'Al-hamdu lillahi 'ala kulli hal (Praise is to Allah in all circumstances).'"

the Prophet (ﷺ) used to say: "Al-hamdu lillahi 'ala kulli hal. Rabbi a'udhu bika min hali ahlin-nar (Praise is to Allah in all circumstances, O Allah, I seek refuge with You from the situation of the people of Hell)."

the Messenger of Allah (ﷺ) said: 'Allah does not bestow a blessing upon any slave and he says: 'Al-hamdu Lillah (praise is to Allah),' except that what he gives (the praise) is better than what he received (the blessing)."

the Messenger of Allah (ﷺ) said: 'Two words which are light on the tongue and heavy in the Balance, and beloved to the Most Merciful: Subhan-Allah wa bi hamdihi, Subhan-Allahil-'Azim (Glory and praise is to Allah, glory is to Allah the Almighty)."

the Messenger of Allah (ﷺ) passed by him when he was planting a plant, and said: "O Abu Hurairah, what are you planting?" I said: "A plant for me." He said: "Shall I not tell you of a plant that is better than this?" He said: "Of course, O Messenger of Allah." He said: "Say: 'Subhan-Allah, wal-hamdu-lillah, wa la ilaha illallah, wa Allahu Akbar (Glory is to Allah, praise is to Allah, none has the right to be worshiped but Allah and Allah is the Most Great.)' For each one a tree will be planted for you in Paradise."

"The Messenger of Allah (ﷺ) passed by her when he prayed the morning prayer, or after he prayed the morning prayer, and she was remembering Allah. He came back when the sun had risen" - or he (one of the narrators) said, "at midday - and she was still doing that. He said: 'I have said four words, three times, since I left you, and they are greater and weigh more heavily than what you have said. They are: Subhan-Allahi 'adada khalqiha, Subhan-Allahi rida nafsihi, Subhan-Allahi zinata 'arshihi, Subhan-Allah midada kalimatihi (Glory is to Allah, as much as the number of His creation, glory is to Allah as much as pleases Him, glory is to Allah as much as the weight of His Throne, glory is to Allah as much as the ink of His words'."

the Messenger of Allah (ﷺ) said: "What you mention of glory of Allah, of Tabsih (Subhan-Allah), Tahlil (Allahu-Akbar) and Tahmid (Al-Hamdu lillah), revolves around the Throne, buzzing like bees, reminding of the one who said it. Wouldn't any one of you like to have, or continue to have, something that reminds of him (in the presence of Allah)?'"

"I came to the Messenger of Allah (ﷺ) and said: 'O Messenger of Allah, tell me of a (good) deed, for I have become old and weak and overweight.' He said: 'Proclaim the greatness of Allah (say Allahu Akbar) one hundred times, praise Allah (say Al-Hamdu Lillah) one hundred times, and glorify Allah (say Subhan-Allah) one hundred times. (That is) better than one hundred horses bridled and saddled for the sake of Allah, better than one hundred sacrificial camels, and better than (freeing) one hundred slaves.'"

the Prophet (ﷺ) said: "(There are) four that are the best of words, and it does not matter with which you begin: Subhan-Allah, wal-Hamdu-Lillah, wa la ilaha illallah, wa Allahu Akbar (Glory is to Allah, praise is to Allah, none has the right to be worshiped but Allah and Allah is the Most Great)."

the Messenger of Allah (ﷺ) said: "Whoever says: Subhan Allahi wa bi hamdihi (Glory and praise is to Allah) one hundred times, his sins will be forgiven even if they were like the foam of the sea.'"

"The Messenger of Allah (ﷺ) said to me: 'You should recite Subhan-Allah, wal-Hamdu-Lillah, wa la ilahah illallah, wa Allahu Akbar (Glory is to Allah, praise is to Allah, none has the right to be worshiped but Allah, and Allah is the Most Great), for it sheds sins like the tree sheds its leaves.'"

"We used to count that the Messenger of Allah (ﷺ) said one hundred times in a gathering: 'Rabbighfirli wa tub `alayya innaka Antat-Tawwabur-Rahim (O Allah forgive me and accept my repentance, for You are the Accepter of repentance, the Most Merciful).'"

the Messenger of Allah (saas) said: 'I seek the forgiveness of Allah and repent to Him one hundred times each day.'
