"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.'"

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

the Messenger of Allah said: "Whoever persists in asking for forgiveness, Allah will grant him relief from every worry, and a way out from every hardship, and will grant him provision from (sources) he could never imagine."

of Allah (saas) said: "Every deed of the son of Adam will be multiplied for him, between ten and seven hundred times for each merit. Allah said: 'Except for fasting, for it is for Me and I shall reward for it.'" (sahih)

"The Messenger of Allah (saas) said to me: "Shall I not tell you of a treasure which is one of the treasures of Paradise?' I said: 'Yes, O Messenger of Allah.' He said: 'La hawla wa la quwwata illa billah (There is no power and no strength except with Allah).'" (sahih)

his mother Su'da Al-Murriyyah said: "Umar bin Khattab passed by Talhah, after the Messenger of Allah(ﷺ) had died, and said: 'Why do you look so sad? Are you upset because your cousin has been appointed leader?' He said: 'No, but I heard the Messenger of Allah(ﷺ) say: "I know a word which no one says at the time of death but it will be light in his record of deeds, and his body and soul will find comfort in it at the time of death," -but I did not ask him about it before he died.' He ('Umar) said: ' I know what it is. It is what he wanted his uncle (Abu Talib) to say, and if he had known anything that would be more effective in saving him, he would have told him to say it.'"

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: "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) 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 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)."

"I passed by the Prophet (saas) and he said to me: 'O Hazim, say often: "La hawla wa la quwwata illa billah (there is no power and no strength except with Allah)," for it is one of the treasures of Paradise.'"
