The Fasting Person is far from Hell
As is narrated by Abu Hurayra, may Allah be pleased with him, Prophet Muhammad, peace and blessings be upon him, said:
"Whoever fasts one day for the acceptance of Allah, Allah keeps his/her face seventy years away from Hell in return for this one day." (Nasai, Siyam: 44)
Ramadan is the Salvation from Hell
Narrated from Abu Hurayra, may Allah be pleased with him, Prophet Muhammad (PBUH) said:
"When the first night of Ramadan comes, Allah regards His creation with mercy. Whichever servant Allah regards with mercy, He does not torment him/her, eternally. Each day of Ramadan, Allah saves one million people from Hell who deserve going to Hell.
When the 27th night of Ramadan comes, angels surge and Allah al-Jabbar (the Irresistible) reflects Himself with His light, which nobody can depict and calls out to the angels, who are to make celebrations the next day:
“O community of angels! What is the due of the worker who fulfills his job thoroughly?”
“He is given his due completely.”
Thereupon, Allah says:
“I appoint you witnesses that I have forgiven them all.” (at-Targhb wa’t-Tarhib, 2:434)
The Gap between the Fasting Person and Hell
According to the narration of Abu'd Darda, may Allah be pleased with him, Prophet Muhammad (PBUH) said:
"Whoever fasts one day for the acceptance of Allah, on the Day of Resurrection, Allah creates a gap between him and Hell, as wide as the heavens and the earth."
(Tirmidhi, Jihad: 3; at-Targhib va’t-Tarhib, 2:86)
