A man with honor passed by him while he was in the city market and greeted him. Alqamah said to him, "O so-and-so, you have a heart and a right. I have seen you enter upon these princes and speak to them as Allah wills you to speak. I have heard Bilal ibn Al-Harith Al-Muzani, the companion of the Messenger of Allah (ﷺ), say: The Messenger of Allah (ﷺ) said: 'Verily, one of you speaks a word from Allah's pleasure, not realizing how far it reaches, but Allah writes His Pleasure therewith until the Day he shall meet Him. And verily, one of you speaks a word from Allah's displeasure, not realizing how far it reaches, but Allah writes His displeasure therewith until the Day he shall meet Him.'" Alqamah said, "Woe to you! Consider what you say and what you speak. Much of what I have heard from Bilal ibn Al-Harith has prevented me from what you are saying. Malik ibn Anas also shortened the narration of this Hadith from Muhammad ibn Amr, and did not mention Alqamah ibn Waqqas."
مَرَّ بِهِ رَجُلٌ لَهُ شَرَفٌ وَهُوَ بِسُوقِ الْمَدِينَةِ فَسَلَّمَ عَلَيْهِ فَقَالَ لَهُ عَلْقَمَةُ يَا فُلَانُ إِنَّ لَكَ رَحِمًا وَلَكَ حَقًّا وَإِنِّي رَأَيْتُكَ تَدْخُلُ عَلَى هَؤُلَاءِ الْأُمَرَاءِ فَتَتَكَلَّمُ عِنْدَهُمْ بِمَا شَاءَ اللَّهُ أَنْ تَكَلَّمَ وَإِنِّي سَمِعْتُ بِلَالَ بْنَ الْحَارِثِ الْمُزَنِيَّ صَاحِبَ رَسُولِ اللَّهِ ﷺ يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ «إِنَّ أَحَدَكُمْ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ رِضْوَانِ اللَّهِ مَا يَظُنُّ أَنْ تَبْلُغَ مَا بَلَغَتْ فَيُكْتَبُ اللَّهُ لَهُ بِهَا رِضْوَانَهُ إِلَى يَوْمِ يَلْقَاهُ وَإِنَّ أَحَدَكُمْ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ سَخَطِ اللَّهِ مَا يَظُنُّ أَنْ تَبْلُغَ مَا بَلَغَتْ فَيُكْتَبُ اللَّهُ عَلَيْهِ بِهَا سَخَطَهُ إِلَى يَوْمِ يَلْقَاهُ» قَالَ عَلْقَمَةُ وَيْحَكَ فَانْظُرْ مَاذَا تَقُولُ وَمَاذَا تَتَكَلَّمُ بِهِ؟ فَرُبَّ كَلَامٍ مَنَعَنِي مَا سَمِعْتُهُ مِنْ بِلَالِ بْنِ الْحَارِثِ «قَصَرَ مَالِكُ بْنُ أَنَسٍ بِرِوَايَةِ هَذَا الْحَدِيثِ عَنْ مُحَمَّدِ بْنِ عَمْرِو وَلَمْ يَذْكُرْ عَلْقَمَةَ بْنَ وَقَّاصٍ»
