Hadith on Words: Single word can earn wrath or pleasure of Allah

Bilal ibn al-Harith reported: The Messenger of Allah, peace and blessings be upon him, said, “Verily, one of you speaks a word pleasing to Allah, thinking it does not amount to much, yet by it Allah decrees his pleasure with him until the day he meets him. Verily, one of you speaks a word displeasing to Allah, thinking it does not amount to much, yet Allah decrees his displeasure with him until the day he meets him.”

عن بلال بن الحارث قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ أَحَدَكُمْ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ رِضْوَانِ اللَّهِ مَا يَظُنُّ أَنْ تَبْلُغَ مَا بَلَغَتْ فَيَكْتُبُ اللَّهُ لَهُ بِهَا رِضْوَانَهُ إِلَى يَوْمِ يَلْقَاهُ وَإِنَّ أَحَدَكُمْ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ سَخَطِ اللَّهِ مَا يَظُنُّ أَنْ تَبْلُغَ مَا بَلَغَتْ فَيَكْتُبُ اللَّهُ عَلَيْهِ بِهَا سَخَطَهُ إِلَى يَوْمِ يَلْقَاهُ
