Prophet saas used to seek refuge with Allah from cowardice, miserliness, old age, the torment of the grave and the tribulation of the heart. (Da'if)(One of the narrators) Waki' said: "Meaning when a man dies in a state of tribulation (Fitnah) and does not ask Allah to forgive him."

when a man had come to the Messenger of Allah (saas), he heard him say: "O Messenger of Allah, what should I say when I ask of Allah?" He said: "Say: Allahumma-ghfirli warhamni wa 'afini warzuqni (O Allah, forgive me, have mercy on me, keep me safe and sound and grant me provision)," and he held up his four fingers apart from the thumb and said: "These combine your religious and worldly affairs."

the Messenger of Allah (saas) taught her this supplication: "Allahumma inni as'aluka minal-khayri kullihi, 'ajilihi wa ajilihi, ma 'alimtu minhu wa ma la a'lam. Wa a'udhu bika minash-sharri kullihi, 'ajilihi wa ajilihi, ma 'alimtu minhu wa ma la a'lam. Allahumma inni as'aluka min khayri ma sa'alaka 'abduka wa nabiyyuka, wa a'udhu bika min sharri ma 'adha bihi 'abduka wa nabiyyuka. Allahumma inni as'alukal-jannatah wa ma qarrab ilayha min qawlin aw 'amalin, wa a'udhu bika minan-nari wa ma qarraba ilayha min qawlin aw 'amalin, wa as'aluka an taj'al kulla qada'in qadaytahuli khayran (O Allah, I ask You for all that is good, in this world and in the Hereafter, what I know and what I do not know. O Allah, I seek refuge with You from all evil, in this world and in the Hereafter, what I know and what I do not know. O Allah, I ask You for the good that Your slave and Prophet has asked You for, and I seek refuge with You from the evil from which Your slave and Prophet sought refuge. O Allah, I ask You for Paradise and for that which brings one closer to it, in word and deed, and I seek refuge in You from Hell and from that which brings one closer to it, in word and deed. And I ask You to make every decree that You decree concerning me good)."

the Messenger of Allah (saas) said to a man: "What do you say during your prayer?" He said: "I recite the Tashah-hud then I ask for Allah for Paradise and see refuge with Him from Hell, but by Allah I do not understand your whispering or the whispering of Mu'adh." He said: "It is concerning them (Paradise and Hell) that we are whispering."

"A man come to the Prophet (saas) and said: 'O Messenger of Allah, what supplication is best?' He said: 'Ask your Lord for forgiveness and to be kept safe and sound in this world and in the Hereafter.' Then (the man) came the next day and said: 'O Messenger of Allah, what supplication is best?' He said: 'Ask your Lord for forgiveness and to be kept safe and sound in this world and in the Hereafter.' Then (the man) came the third day and said: 'O Prophet of Allah, what supplication is best?' He said: 'Ask your Lord for forgiveness and to be kept safe and sound in this world and in the Hereafter, for if you are forgiven and kept safe and sound in this world and the Hereafter, you will have succeeded.'"

he heard Abu Bakr, when the Prophet (saas) had passed away, saying: "The Messenger of Allah (saas) stood in this place where I am standing, last year." Then Abu Bakr wept, then he said: "You must adhere to the truth, for with it comes righteousness and they both lead to Paradise. And you must beware of lying for with it comes immorality, and they both lead to Hell. Ask Allah for Al-Mu'afah, for no one is given anything after certainty that is better than Mu'afah. Do not envy one another, do not hate one another, do not sever ties with one another, do not turn your backs on one another and be, O slaves of Allah, brothers."

"O Messenger of Allah, what do you think I should say in my supplication, if I come upon Laylatul-Qadr?" He said: "Say: 'Allahumma innaka 'afuwwun tuhibbul-'afwa, fa'fu 'anni (O Allah, You are Forgiving and love forgiveness, so forgive me).'"

"The Messenger of Allah (saas) said: 'There is no supplication that a person can say that is better than: Allahumma inni as'aluka al-mu'afah fid-dunya wal-akhirah (O Allah, I ask You for Al-Mu'afah in this world and in the Hereafter).'"

the Messenger of Allah (saas) said: "May Allah have mercy on us and on our brother of 'Ad." (i.e., Prophet Hud alay-salaam).

the Messenger of Allah (saas) said: "It is necessary that you do not become hasty." It was said: "What does being hasty mean, O Messenger of Allah?" He said: "When one says: 'I supplicated to Allah but Allah did not answer me.'"

Messenger of Allah (saas) said: "No one among you should say: "O Allah, forgive me if You will.' Let him be definite in his asking, and no one can compel Allah."

the Messenger of Allah (saas) said: "The Greatest Name of Allah is in these two Verses: And your Ilah (God) is One Ilah (God - Allah), La Ilaha Illa Huwa (none has the right to be worshipped but He), the Most Gracious, the Most Merciful.' And at the beginning of Surah Al 'Imran."

The Greatest Name of Allah, if He is called by which He will respond, is in three Surah: Al-Baqarah, Al 'Imran and Ta-Ha. (Hasan)Another chain for something similar from Al-Qasim, from Abu Umamah, from the Prophet (saas).

Messenger of Allah (saas) said: "Whoever does not call upon Allah, He will be angry with him."

"The Prophet (saas) heard a man say: 'Allahumma! Inni as'aluka bi-annaka Antallahul-Ahadus-Samad, alladhi lam yalid wa lam yuwlud, wa lam yakun lahu kufuwan ahad (O Allah! I ask You by virtue of Your being Allah, the One, the Self-Sufficient Master, Who begets not nor was begotten, and there is none co-equal or comparable to Him).' The Messenger of Allah (saas) said: 'He has asked Allah by His Greatest Name, which if He is asked thereby He gives, and if He is called upon thereby He answers.'"

"The Prophet (saas) heard a man say: 'Allahumma! Inni as'aluka bi-anna lakal-hamd. La ilaha illa Anta, wahdaka la sharika laka. Al-Mannan. Badi'us-samawati wal-ard. Dhul-jalali wal-ikram (O Allah! I ask You by virtue of the fact that all praise is due to You; none has the right to be worshiped but You alone, and You have no partner or associate, the Bestower, the Originator of the heavens and the earth, the Possessor of majesty and honor.' He (saas) said: 'He has asked Allah by His Greatest Name which, if He is asked thereby He gives and if He is called upon thereby He answers.'"

"I heard the Messenger of Allah (saas) say: 'Allahumma! Inni asa'luka bismikat-tahirit-tayyibil-mubarak al-ahabbi ilaika, alladhi idha du'ita bihi ajabta, wa idha su'ilta bihi a'taita, wa idhasturhimta bihi rahimta, wa idhastufrijta bihi farrajta (O Allah! I ask You by Your pure, good and blessed Name which is most beloved by You, which if You are called thereby You answer, and if You as asked thereby You give, if You are asked for mercy thereby You bestow mercy, and if You are asked for relief (from distress) thereby You grant relief.'"She said: "He said one day: 'O 'Aishah, do you know that Allah has told me the Name which, if He is called thereby, He responds?' I said: 'O Messenger of Allah, may my father and mother be ransomed for you! Teach it to me.' He said: 'You should not learn it, O 'Aishah.' So I moved aside and sat for a while, then I got up and kissed his head, then I said: 'O Messenger of Allah, teach it to me.' He said: 'You should not learn it, O 'Aishah, and I should not teach it to you, for you should not ask for any worldly things thereby.'" She said: "So I got up and performed ablution, then I prayed two Rak'ah, then I said: 'O Allah, I call upon Allah, and I call upon You, Ar-Rahman (the Most Gracious), and I call upon You, Al-Barr Ar-Rahim (The Most Kind, the Most Merciful), and I call upon You by all Your beautiful Names, those that I know and those that I do not know, (asking) that You forgive me and have mercy on me.' The Messenger of Allah (saas) smiled, then he said: 'It is among the names by which you called upon (Allah).'"
