The Prophet said: "The best of prayers for forgiveness is for a person to say: 'Allahumma, anta rabbi, la ilaha illa anta, khalaqtani wa ana 'abduka, wa ana 'ala 'ahdika wa wa'dika mastata'tu, a'udhu bika min sharri ma sana'tu, abuw'u laka bidhanbi, wa abuw'u laka bini'matika 'alayya faghfirli, fa innahu la yaghfirudh-dhunuba illa anta (O Allah, You are my Lord, there is no god but You. You have created me and I am Your slave and I am keeping my promise and covenant to You as much as I can. I seek refuge with You from the evil of what I do. I acknowledge Your blessing and I acknowledge my sin, so forgive me, for there is none who can forgive sin except You.)' If he says this in the morning, believing in it firmly, and dies on that day before evening comes, he will enter Paradise, and if he says it in the evening, believing firmly in it, and dies before morning comes, he will enter Paradise." Al-Walid bin Tha'labah contradicted him.
Sunan an-Nasa'i Book 50, Hadith 95
"The sun eclipsed during the time of the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) got up to pray, and those who were with him also got up. He stood for a long time, then he bowed for a long time, then he raised his head and (then) prostrated for a long time. Then he raised his head and sat for a long time. Then he prostrated for a long time, then he raised his head and stood up, and he did in the second rak'ah the same as he had done in the first, standing, bowing, prostrating and sitting. He started blowing and weeping at the end of his prostration in the second rak'ah, saying: 'You did not tell me that You would do that while I was still among them; You d not tell me that You would do that while we are asking You for forgiveness.' Then he raised his head and the eclipse ended. The Messenger of Allah (ﷺ) stood and addressed the people. He praised and glorified Allah then he said: "The sun and moon are two of the signs of Allah (SWT), the Mighty and Sublime. If you see either of them being eclipsed, then hasten to remember Allah (SWT), the Mighty and Sublime. By the One in Whose Hand is the soul of Muhammad, Paradise was brought so near to me that if I had stretched out my hand, I could have taken some of its fruits. And Hell was brought so near to me that I tried to ward it off for fear it may overwhelm you. I saw therein a woman from Himyar who was being punished because of a cat she tied up, not leaving it free to eat of the vermin of the earth, nor feeding it or giving it water, until it died. I saw it biting her when she came and biting her backside when she went. And I saw the owner of the Sabtiyatain, the brother of Banu As-Da'da, being pushed with a two-pronged stick in the Fire. And I saw the owner of the stick with a crooked end, who used to steal from the Hajj pilgrims with that crooked stick, leaning on his stick in Hell and saying: 'I am the thief with the crooked stick.'"
Sunan an-Nasa'i Book 16, Hadith 24
I said, "O Allah's Prophet! We are living in a land ruled by the people of the Scripture; Can we take
our meals in their utensils? In that land there is plenty of game and I hunt the game with my bow and
with my hound that is not trained and with my trained hound. Then what is lawful for me to eat?" He
said, "As for what you have mentioned about the people of the Scripture, if you can get utensils other
than theirs, do not eat out of theirs, but if you cannot get other than theirs, wash their utensils and eat
out of it. If you hunt an animal with your bow after mentioning Allah's Name, eat of it. and if you hunt
something with your trained hound after mentioning Allah's Name, eat of it, and if you hunt
something with your untrained hound (and get it before it dies) and slaughter it, eat of it."
