La Malja'a wa la manja minka illa ilaika. Amantu bikitabika al-ladhi anzalta wa nabiyyika al-ladhi arsalta!

You have created me, and I am Your servant, and I am faithful to Your covenant and promise as much as I can. I seek refuge in You from the evil of what I have done. I acknowledge Your blessings upon me, and I admit my sins. So forgive me, for none forgives sins except You.
(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, abu'u Laka bini`matika `alaiya, wa abu'u laka bidhanbi faghfir lee fa innahu la yaghfiru adhdhunuba illa anta) "
The Prophet 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."

We went to pay a visit to Khabbab (who was sick) and he had been branded (cauterized) at seven places in his body. He said, "Our companions who died (during the lifetime of the Prophet) left (this world) without having their rewards reduced through enjoying the pleasures of this life, but we have got (so much) wealth that we find no way to spend It except on the construction of buildings Had the Prophet not forbidden us to wish for death, I would have wished for it.' We visited him for the second time while he was building a wall. He said, A Muslim is rewarded (in the Hereafter) for whatever he spends except for something that he spends on building."

Wa lakaI-hamdu; Anta-l-,haqqun, wa wa'daka haqqun, wa qauluka haqqun, wa liqauka haqqun, wal-jannatu haqqun, wannaru haqqun, was-sa atu haqqun, wan-nabiyyuna huqqun, Mahammadun haqqun, Allahumma laka aslamtu, wa Alaika tawakkaltu, wa bika amantu, wa ilaika anabtu, wa bika Khasamtu, wa ilaika hakamtu, faghfirli ma qaddamtu wa ma akh-khartu, wa ma asrartu, wa ma a'lantu.

The most beloved names to `Ali was Abu Turab, and he used to be pleased when we called him by it, for none named him Abu Turab (for the first time), but the Prophet.

The Prophet came to him while his (`Ali's) back was covered with dust. The Prophet started removing the dust from his back, saying, "Get up, O Abu Turab!"
