SUPPLICATIONS
Narrated Shaddad bin Aus:
The Prophet (ﷺ) said "The most superior way of asking for forgiveness from Allah is: 'Allahumma anta Rabbi la ilaha illa anta, Anta Khalaqtani wa ana Abduka, wa ana 'ala ahdika wa wa'dika mastata'tu, Audhu bika min Sharri ma sana'tu, Abu 'u Laka bini'matika 'alaiya, wa Abu 'u laka bidhanbi faghfir lee fa innahu la yaghfiru adhdhunuba illa anta." The Prophet (ﷺ) added. "If somebody recites it during the day with firm faith in it, and dies on the same day before the evening, he will be from the people of Paradise; and if somebody recites it at night with firm faith in it, and dies before the morning, he will be from the people of Paradise."
IN ANOTHER
Narrated Al-Bara bin `Azib:
Allah's Messenger (ﷺ) said to me, "When you want to go to bed, perform ablution as you do for prayer, then lie down on your right side and say: 'Allahumma aslamtu wajhi ilaika, wa fawwadtu 'amri ilaika wa alja'tu dhahri ilaika, raghbatan wa rahbatan ilaika, la malja'a wa la manja minka illa ilaika. Amantu bikitabik al-ladhi anzalta wa binabiyyika al-ladhi arsalta'. If you should die then (after reciting this) you will die on the religion of Islam (i.e., as a Muslim); so let these words be the last you say (before going to bed)" While I was memorizing it, I said, "Wa birasulika al-ladhi arsalta (in Your Apostle whom You have sent).' The Prophet (ﷺ) said, "No, but say: Wa binabiyyika al-ladhi arsalta (in Your Prophet whom You have sent).
IN ANOTHER HADITH
Narrated Ibn `Abbas:
One night I slept at the house of Maimuna. The Prophet (ﷺ) woke up, answered the call of nature, washed his face and hands, and then slept. He got up (late at night), went to a water skin, opened the mouth thereof and performed ablution not using much water, yet he washed all the parts properly and then offered the prayer. I got up and straightened my back in order that the Prophet (ﷺ) might not feel that I was watching him, and then I performed the ablution, and when he got up to offer the prayer, I stood on his left. He caught hold of my ear and brought me over to his right side. He offered thirteen rakat in all and then lay down and slept till he started blowing out his breath as he used to do when he slept. In the meantime Bilal informed the Prophet (ﷺ) of the approaching time for the (Fajr) prayer, and the Prophet offered the Fajr (Morning) prayer without performing new ablution. He used to say in his invocation, Allahumma ijal fi qalbi nuran wa fi basari nuran, wa fi sami nuran, waan yamini nuran, waan yasari nuran, wa fawqi nuran, wa tahti nuran, wa amami nuran, wa khalfi nuran, wajal li nuran." Kuraib (a sub narrator) said, "I have forgotten seven other words, (which the Prophet (ﷺ) mentioned in this invocation). I met a man from the offspring of Al-`Abbas and he narrated those seven things to me, mentioning, '(Let there be light in) my nerves, my flesh, my blood, my hair and my body,' and he also mentioned two other things."
