Hadith 823
Sayyiduna Anas (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: "Allah, the Mighty and Majestic, will say on the Day of Resurrection: 'Whoever has in his heart even a mustard seed's weight of faith, take him out of the Fire.' Then Allah, the Exalted, will say: 'By My Honor and Majesty! I will not treat the one who believed in Me at any time of the night or day like the one who did not believe in Me.'"
