"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).'"
Sunan Ibn Majah Book 34, Hadith 33
Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn
Yasar from Abdullah as-Sanabihi that the Messenger of Allah, may Allah
bless him and grant him peace, said, "A trusting slave does wudu and
as he rinses his mouth the wrong actions leave it. As he cleans his
nose the wrong actions leave it. As he washes his face, the wrong
actions leave it, even from underneath his eyelashes. As he washes his
hands the wrong actions leave them, even from underneath his
fingernails. As he wipes his head the wrong actions leave it, even
from his ears. And as he washes his feet the wrong actions leave them,
even from underneath the toenails of both his feet." He added, "Then
his walking to the mosque and his prayer are an extra reward for him."
Muwatta Malik Book 2, Hadith 30
"When the Messenger of Allah (ﷺ) came to Al-Madinah, he alighted in the upper part of Al-Madinah among the tribe called Banu 'Amr bin 'Awf and he stayed with them for fourteen nights. Then he sent for the chiefs of Banu An-Najjar, and they came with their swords by their sides. It is as if I can see the Messenger of Allah (ﷺ) on his she-camel with Abu Bakr riding behind him (on the same camel) and the chiefs of Banu An-Najjar around him, until he dismounted in the courtyard of Abu Ayyub. The Prophet (ﷺ) used to offer the prayer wherever he was when the time for prayer came, and he would pray even in sheepfolds. Then he ordered that the Masjid be built. He sent for the chiefs of Banu An-Najjar, and when they came, he said: 'O Banu An-Najjar, name me a price for this grove of yours.' They said: 'By Allah, we will not ask for its price except from Allah.'" Anas said: "In (that grove) there were graves of idolators, ruins and date-palm trees. The Messenger of Allah (ﷺ) ordered that the graves of the idolators be dug up, the ruins be leveled and the date-palm trees be cut down. The trunks of the trees were arranged so as to form the walls facing the Qiblah. The stone pillars were built at the sides of its gate. They started to move the stones, reciting some lines of verse, and the Messenger of Allah (ﷺ) was with them when they were saying: 'O Allah! There is no good except the good of the Hereafter. So bestow victory on the Ansar and the Muhajirin.'"
Sunan an-Nasa'i Book 8, Hadith 15
A group of the companions of Allah's Messenger (ﷺ) proceeded on a journey till they dismounted near one of
the Arab tribes and requested them to entertain them as their guests, but they (the tribe people) refused
to entertain them. Then the chief of that tribe was bitten by a snake (or stung by a scorpion) and he
was given all sorts of treatment, but all in vain. Some of them said, "Will you go to the group (those
travelers) who have dismounted near you and see if one of them has something useful?" They came to
them and said, "O the group! Our leader has been bitten by a snake (or stung by a scorpion) and we
have treated him with everything but nothing benefited him Has anyone of you anything useful?" One
of them replied, "Yes, by Allah, I know how to treat with a Ruqya. But. by Allah, we wanted you to
receive us as your guests but you refused. I will not treat your patient with a Ruqya till you fix for us
something as wages." Consequently they agreed to give those travellers a flock of sheep. The man
went with them (the people of the tribe) and started spitting (on the bite) and reciting Surat-al-Fatiha
till the patient was healed and started walking as if he had not been sick. When the tribe people paid
them their wages they had agreed upon, some of them (the Prophet's companions) said, "Distribute
(the sheep)." But the one who treated with the Ruqya said, "Do not do that till we go to Allah's
Apostle and mention to him what has happened, and see what he will order us." So they came to
Allah's Messenger (ﷺ) and mentioned the story to him and he said, "How do you know that Surat-al-Fatiha is
a Ruqya? You have done the right thing. Divide (what you have got) and assign for me a share with
you."
