From 'Urwah [bin Az-Zubair], and Sulaiman bin Yasar, that they reported to him from Abu Hurairah that the Prophet (saws) said: "Whoever fasts a day in the cause of Allah, Allah shall distance him from the Fire by seventy autumns." One of them said "seventy" and the other said: "forty".

[Abu 'Eisa said:] This Hadith is a Gharib Hadith from this route. Abu Al-Aswad's name is Muhammad bin 'Abdur-Rahman bin Nawfal Al-Asadi Al-Madani.

There are narrations on this topic from Abu Sa'eed, Anas, 'Uqbah bin 'Amir, and Abu Umamah

The Prophet once came out and offered the funeral prayer for the martyrs of Uhud, and proceeded to the pulpit and said, "I shall be your predecessor and a witness on you, and I am really looking at my sacred Fount now, and no doubt, I have been given the keys of the treasures of the world. By Allah, I am not afraid that you will worship others along with Allah, but I am afraid that you will envy and fight one another for worldly fortunes."

One day the Prophet went out and offered the funeral prayers of the martyrs of Uhud and then went up the pulpit and said, "I will pave the way for you as your predecessor and will be a witness on you. By Allah! I see my Fount (Kauthar) just now and I have been given the keys of all the treasures of the earth (or the keys of the earth). By Allah! I am not afraid that you will worship others along with Allah after my death, but I am afraid that you will fight with one another for the worldly things."

The Prophet went out and offered the funeral prayer for the martyrs of the (battle of) Uhud and then ascended the pulpit and said, "I am your predecessor and I am a witness against you. By Allah, I am now looking at my Tank-lake (Al-Kauthar) and I have been given the keys of the treasures of the earth (or the keys of the earth). By Allah! I am not afraid that after me you will worship others besides Allah, but I am afraid that you will start competing for (the pleasures of) this world."

The Prophet said to me, "You fast daily all the year and pray every night all the night?" I replied in the affirmative. The Prophet said, "If you keep on doing this, your eyes will become weak and your body will get tired. He who fasts all the year is as he who did not fast at all. The fasting of three days (a month) will be equal to the fasting of the whole year." I replied, "I have the power for more than this." The Prophet said, "Then fast like the fasting of David who used to fast on alternate days and would never flee from the battle field, on meeting the enemy."

I heard the Prophet saying, "Indeed, anyone who fasts for one day for Allah's Pleasure, Allah will keep his face away from the (Hell) fire for (a distance covered by a journey of) seventy years."

'Ashura' (i.e. the tenth of Muharram) was a day on which the tribe of Quraish used to fast in the prelslamic period of ignorance. The Prophet also used to fast on this day. So when he migrated to Medina, he fasted on it and ordered (the Muslims) to fast on it. When the fasting of Ramadan was enjoined, it became optional for the people to fast or not to fast on the day of Ashura.

The news of my daily fasting and praying every night throughout the night reached the Prophet. So he sent for me or I met him, and he said, "I have been informed that you fast everyday and pray every night (all the night). Fast (for some days) and give up fasting (for some days); pray and sleep, for your eyes have a right on you, and your body and your family (i.e. wife) have a right on you." I replied, "I have more power than that (fasting)." The Prophet said, "Then fast like the fasts of (the Prophet) David". I said, "How?" He replied, "He used to fast on alternate days, and he used not to flee on meeting the enemy." I said, "From where can I get that chance?" (`Ata' said, "I do not know how the expression of fasting daily throughout the life occurred.") So, the Prophet said, twice, "Whoever fasts daily throughout his life is just as the one who does not fast at all."

That the Prophet (saws) said, "Whoever fasts a day in the cause of Allah, Allah shall put between him and the Fire a trench whose distance is like that between the heavens and the earth."

This Hadith is Gharib as a narration of Abu Umamah.

Whenever Ibn `Umar started the prayer with Takbir, he used to raise his hands: whenever he bowed, he used to raise his hands (before bowing) and also used to raise his hands on saying, "Sami`a l-lahu liman hamidah", and he used to do the same on rising from the second rak`a (for the 3rd rak`a). Ibn `Umar said: "The Prophet used to do the same."
