Narrator:Abu Hurayrah
حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُنِيرٍ، سَمِعَ أَبَا النَّضْرِ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ ـ يَعْنِي ابْنَ دِينَارٍ ـ عَنْ أَبِيهِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ "
إِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ رِضْوَانِ اللَّهِ لاَ يُلْقِي لَهَا بَالاً، يَرْفَعُ اللَّهُ بِهَا دَرَجَاتٍ، وَإِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ سَخَطِ اللَّهِ لاَ يُلْقِي لَهَا بَالاً يَهْوِي بِهَا فِي جَهَنَّمَ "
Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "A person may utter a word pleasing to Allah, the Almighty, without considering it of any significance, and because of it Allah raises his ranks; and a person may utter a word displeasing to Allah, the Almighty, without considering it of any significance, and because of it he sinks down into Hellfire." Abu ‘Abdur-Rahmān Bilāl ibn al-Hārith al-Muzani (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "A person may utter a word pleasing to Allah, the Almighty, and he does not think it will yield such a result, and because of it Allah writes for him His pleasure until the Day he will meet Him; and a person may utter a word displeasing to Allah, the Almighty, and he does not think it will yield such a result, and because of it Allah writes for him His displeasure until the Day he will meet Him."
