Praise be to Allah,
Sufyaan [ibn ‘Uyaynah] narrated to us from ‘Amr [ibn Deenaar] from Jaabir ibn ‘Abdullaah who said,
“The Prophet (peace and blessings be on him) said, ‘Allah will bring some people out of Hell and admit them into Paradise.”‘
(Musnad Ahmad, Vol. 3, p. 308. The isnaad of this hadeeth is Saheeh according to the conditions set by al-Bukhaaree and Muslim.)
