Narrated Abu Sa’id Al-Khudri:
The Prophet said, “You will follow the ways of those nations who were before you, span by span and cubit by cubit (i.e., inch by inch) so much so that even if they entered a hole of a mastigure, you would follow them.” We said, “O Allah’s Apostle! (Do you mean) the Jews and the Christians?” He said, “Whom else?”

Narrated Jabir bin ‘Abdullah:
Allah’s Apostle said, “Whoever after listening to the Adhan says, ‘Allahumma Rabba hadhihi-d-da’ watit-tammati was-salatil qa’imati, ati Muhammadan al-wasilata wal-fadilata, wab’ athhu maqaman mahmudan-il-ladhi wa’ adtahu (O Allah! Lord of this perfect call (of not ascribing partners to You) and of the regular prayer which is going to be established! Kindly give Muhammad the right of intercession and superiority and send him (on the Day of Judgment) to the best and the highest place in Paradise which You promised him)’, then intercession for me will be permitted for him on the Day of Resurrection“).
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)
