Dought & clear, - - Saheeh (sound) hadeeths, - Are there any saheeh ahaadeeth which speak of the ransoming of the living and the deadduring Ramadaan?.

I heard from someone that Allaah ransoms just one of the dead Muslims
every night, and that He does not ransom any of the living except on
the last night of Ramadaan, when He ransoms the same number as the
number of dead whom He ransomed during the month. Is this true?.
Praise be to Allaah.
After researching the matter, we did not find any ahaadeeth which say
such a thing.
There are ahaadeeth which say that Allaah ransoms people from the Fire
during Ramadaan, and that happens every night.
Some of these ahaadeeth are saheeh (sound), some are da'eef (weak),
and some are mawdoo' (fabricated).
Among the saheeh ahaadeeth which speak of that are the following:
1 – It was narrated that Abu Hurayrah (may Allaah be pleased with him)
said: The Messenger of Allaah(peace and blessings of Allaah be upon
him) said: "When the first night of Ramadaan comes, the devils and
mischievous jinn are chained up, and the gates of Hell are closed, and
none of its gates are opened. The gates of Paradise are opened and
none of its gates are closed. And a caller cries out: 'O seeker of
good, proceed; O seeker of evil, desist.' And Allaah has people whom
He frees (from the Fire), and that happens every day."
Narrated by al-Tirmidhi, 682; Ibn Maajah, 1642; classed as hasan by
Shaykh al-Albaani inSaheeh al-Jaami', 759.
2 – It was narrated that Jaabir (may Allaah be pleased with him) said:
The Messenger of Allaah(peace and blessings of Allaah be upon him)
said: "At every breaking of the fast Allaah has people whom He redeems
from the Fire, and that happens every night."
Narrated by Ahmad, 21698; Ibn Maajah, 1643; classed as saheeh by
Shaykh al-Albaani inSaheeh Ibn Maajah.
The da'eef (weak) and mawdoo' (fabricated) ahaadeeth that have been
narrated on this topic include the following:
1 – The report narrated from Abu Hurayrah (may Allaah be pleased with
him), according to which the Messenger of Allaah(peace and blessings
of Allaah be upon him) said: "When the first night of Ramadaan comes,
Allaah looks at His creation, and if Allaah looks at a person He will
never punish him. And every day Allaah has one thousand thousand whom
He ransoms from the Fire. On the twenty-ninth night Allaah ransoms a
number equivalent to the number whom He has already ransomed during
the entire month."
This is a mawdoo' hadeeth. SeeDa'eef al-Targheeb, 591 andal-Silsilah
al-Da'eefah, 5468.
2 – It was narrated from Ibn 'Abbaas (may Allaah be pleased with him)
that he heard the Messenger of Allaah(peace and blessings of Allaah be
upon him) say: "Paradise is scented with incense and adorned
throughout the year, in preparation for the beginning of the month of
Ramadaan. On the first night of the month of Ramadaan, a wind called
al-matheerah comes from beneath the Throne… And on each day of the
month of Ramadaan at the time of breaking the fast, Allaah has one
thousand thousand whom He ransoms from the Fire, all of whom deserved
to go to Hell. And on the last day of the month of Ramadaan, Allaah
ransoms on that day a number equivalent to all those whom He ransomed
from the beginning of the month to the end.
This is a mawdoo' hadeeth. SeeDa'eef al-Targheeb, 594.
3 – It was narrated that al-Hasan said: The Messenger of Allaah(peace
and blessings of Allaah be upon him) said: "Every night of Ramadaan
Allaah has six hundred thousand whom He ransoms from the Fire. And on
the last night Allaah ransoms a number equivalent to those whom He has
already ransomed."
This is a da'eef hadeeth. SeeDa'eef al-Targheeb, 598.
