“Whomsoever of you the door of supplication is opened for, the doors of mercy have been opened for him. And Allah is not asked for anything - meaning - more beloved to Him, than being asked for Al-`Āfiyah.” And the Messenger of Allah (saws) said: “The supplication benefits against that which strikes and that which does not strike, so hold fast, O worshippers of Allah, to supplication.”

Anas told of a man who came to the Prophet and asked him which supplication was most excellent. To this he replied, "Ask your Lord for health and for security from evil in this world and the next." He came to him on the following day, asked the same question, and received a similar reply. Then when he came on the third day he received a similar reply with this addition, "If you are given health and security from evil in this world and the next, you have attained felicity." Tirmidhi and Ibn Majah transmitted it, Tirmidhi saying this is a hasan tradition whose isnad is gharib.

"The Messenger of Allah (SAW) did not raise his hands during any supplication except when praying for rain, when he used to raise his hands so high that the whiteness of his armpits could be seen."

The Messenger of Allah (SAW) said: "People should certainly stop lifting their gaze to the sky when they supplicate during the prayer, or they will lose their eyesight."

Jabir said, "The Prophet. may Allah bless him and grant him peace, used to teach us the istikhara in matters just as if it was a sura of the Qur'an. He said, 'When someone is concerned about something, he should pray two rak'ats and then say, 'O Allah, I ask You for the good by Your knowledge and I ask You for strength by Your power and I ask You for some of Your immense abundant favour, You have the power and I do not. You know and I do not know. You are the Knower of the Unseen Worlds. O Allah, if You know that this affair is good for me in my deen, my livelihood and the end of my affair (or he said 'in the beginning of my affair') and its conclusion, then avert it from me and avert me from it. Decree for me the good wherever it is and then make me content." Then he should state what he needs.'"

The Prophet [SAW] used to say these supplications: "Allahumma inni a'udhu bika min 'ilmin la yanfa'u, wa qalbin la yakhsha'u, wa du'a'in la yasma'u, wa nafsin la tashba'u. (O Allah, I seek refuge with You from knowledge that is of no benefit, a heart that is not humble, a supplication that is not heard and a soul that is not satisfied.)" Then he would say: 'Allahumma inni a'udhu bika min ha'ula'il-arba' (O Allah, I seek refuge with You from these four.)'"

He said, “We used to receive command to make a supplication when the call to the sunset prayer was being made.” Baihaqi transmitted it in ad-Da'awal al-kabir.

"One of the supplications that the Prophet used to say was: 'Allahumma, inni a'udhu bika min 'ilmin la yanfa'u, wa mindu'a'in la yusma'u, wa min qalbin la yakhsha'u, wa min nafsin la tashba'u [O Allah, I seek refuge with You from knowledge that is of no benefit, from a supplication that is not heard, from a heart that does not fear (You) and from a soul that is not satisfied].'"

The Messenger of Allah (SAW) said: "The closest that a person can be to his Lord, the Mighty and Sublime, is when he is prostrating, so increase in supplication then."

"I said: 'O Messenger of Allah, teach me a supplication from which I may benefit.' He said: 'Say: Allahumma 'afini min sharri sam'i, wa basari, wa lisani, wa qalbi, wa sharri mani (O Allah, protect me from the evil of my hearing, my seeing, my tongue and my heart, and the evil of my sperm.)" - Meaning his sexual organ.

The Prophet [SAW] used to seek refuge (with Allah) from four things: From knowledge that is of no benefit, from a heart that does not feel humble, from a supplication that is not heard, and a soul that is never satisfied.

"I said: 'O Messenger of Allah, teach me a supplication from which I may benefit.' He said: 'Say: Allahumma 'afini min sharri sam'i, wa basari, wa lisani, wa qalbi, wa min sharri mani (O Allah, protect me from the evil of my hearing, my seeing, my tongue and my heart, and from the evil of my sperm.)'" - Meaning sexual organ.

The supplication made between the adhan and the iqamah is not rejected.

“O Messenger of Allah, which supplication is the best?” He (saws) said: “Ask Your Lord For Al-`Āfiyah and Al-Mu`āfāh in this world and in the Hereafter.” Then he came to him on the second day and said: “O Messenger of Allah, which supplication is the best?” So he (saws) said to him similar to that. Then he came to him on the third day, so he (saws) said to him similar to that. He (saws) said: “So when you have been given Al-`Āfiyah in this world, and you have been given it in the Hereafter, then you have succeeded.”

“The best of supplication is the supplication of the Day of `Arafah. And the best of what I and the Prophets before me have said is: None has the right to be worshipped but Allah, Alone, without partner, to Him belongs all that exists, and to Him belongs the Praise, and He is powerful over all things. (Lā ilāha illallāh, waḥdahu lā sharīka lahu, lahul-mulku wa lahul-ḥamdu, wa huwa `alā kulli shai’in qadīr).’”

"I asked Zaid bin Kharijah who said: 'I asked the Messenger of Allah (SAW) and he said: Send salah upon me and strive hard in supplication, and say: Alahumma salli 'ala Muhammad wa 'ala ali Muhammad (O Allah, send salah upon Muhammad and upon the family of Muhammad).'"

"The Messenger of Allah [SAW] used to say: 'Allahumma inni a'udhu bika min al-arba': min 'ilmin la yanfa'u, wa min qalbin la yakhsha'u, wa min nafsin la tashba'u, wa min du'a'in la yusma'u (O Allah, I seek refuge in You from four: From knowledge that is of no benefit, from a heart that is not humble, from a soul that is not satisfied and from a supplication that is not answered.)'"

"The Prophet [SAW] used to say: 'Allahumma (O Allah,)' and he mentioned the supplication, and said at the end, 'A'udhu bika an ughtala min tahti (and I seek refuge with You from being swallowed up from beneath me.)'"

Anas reported God’s messsenger as saying, “Supplication is the pith of worship.” Tirmidhi transmitted it.

The Prophet (saws) said: Supplication (du'a') is itself the worship.

(He then recited:) "And your Lord said: Call on Me, I will answer you" (xI.60).

The Prophet (PBUH) said, "Du'a (supplication) is worship."

[Abu Dawud].

The Messenger of Allah used to teach them this supplication as he taught them surahs of the Quran: Allahumma inna na'udhu bika min 'adhabil-qabri wa a'udhu bika min fitnatil-masihid-dajjal, wa a'udhu bika min fitnatil-mahya wal-mamat (O Allah, We seek refuge with You from the torment of Hell, and I seek refuge with You from the torment of the grave, and I seek refuge with You from the trail of Al-Masihid-Dajjal, and I seek refuge with You from the trails of life and death.)"

"I said to the Prophet: 'Your paternal uncle, the old misguided man has died. Who will bury him?' He said: 'Go and bury your father, then do not do anything until you come to me.' So I buried him then I came, and he told me to perform Ghusl and he prayed for me, and he mentioned a supplication that I do not remember."'

The Messenger of Allah [SAW] used to teach them this supplication as he would teach them a Surah of the Qur'an: "Say: 'Allahumma, inni na'uwdhu bika min 'adhabi jahannama, wa a'udhu bika min 'adhabil-qabri, wa a'udhu bika min fitnatil-masihid-dajjali, wa a'udhu bika min fitnatil-mahya wal-mamat (O Allah, we seek refuge with You from the torment of Hell, and I seek refuge with You from the torment of the grave, and I seek refuge with You from the tribulation of Al-Masihid-Dajjal, and I seek refuge with You from the trials of life and death.)'"

Anas said that God’s messenger used to raise his hands in supplication so that the whiteness under his armpits was visible.

"O Allah, I seek refuge in You from a prayer that is of no benefit."

The Messenger of Allah (PBUH) said: "The supplication made between the Adhan and the Iqamah is never rejected."

[Abu Dawud and At-Tirmidhi].

The Prophet (peace be upon him) was not accustomed to raise his hands in any supplication he made except when praying for rain. He would then raise them high enough so much so that the whiteness of his armpits was visible.

Anas said that the Prophet's most frequent supplication was, "O God, bring us blessing in this world, blessing in the next, and guard us from the punishment of hell." (Bukhari and Muslim.)

The Prophet (saws) said: The supplication which gets the quickest answer is that made by one distant Muslim for another.

"The Messenger of Allah [SAW] said: 'Allahumma inni a'udhu bika min 'ilmin la yanfa'u, wa min qalbin la yakhsha'u, wa min nafsin la tashba'u, wa min du'a'in la yusma' (O Allah, I seek refuge with You from knowledge that is of no benefit, a heart that is not humble, a soul that is not satisfied and a supplication that is not heard.)'"

"The Messenger of Allah [SAW] used to say: 'Allahumma inni a'udhu bika min 'ilmin la yanfa'u, wa min qalbin la yakhsha'u, wa min nafsin la tashba'u, wa min du'a'in la yusma' (O Allah, I seek refuge with You from knowledge that is of no benefit, a heart that is not humble, a soul that is not satisfied and a supplication that is not heard.)'"

Grant me forgiveness from You and have mercy on me for You are the Oft-Forgiving, Most Merciful.)'"

The Prophet (saws) said: When you pray over the dead, make a sincere supplication for him.
