The Prophet (SAWS) is narrated to have said:
“Jibreel said to me, ‘May Allaah rub his nose in the dust, that person to who Ramadaan comes and his sins are not forgiven,’ and I said, ‘Ameen’. Then he said, ‘May Allaah rub his nose in the dust, that person who lives to see his parents grow old, one or both of them, but he does not enter Paradise (by not serving them) and I said, ‘Ameen’. Then he said, ‘May Allaah rub his nose in the dust, that person in whose presence you are mentioned and he does not send blessings upon you,’ and I said, ‘Ameen.’” (Tirmidhi, Ahmad, others. Saheeh by al-Albaani)
