وَعَنْ سِمَاكِ بْنِ حَرْبٍ قَالَ سَمِعْتُ النُّعْمَانَ بْنَ بَشِيرٍ رَضِيَ اللَّهُ عَنْهُ يَخْطُبُ وَعَلَيْهِ خَمِيصَةٌ لَهُ فَقَالَ لَقَدْ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَخْطُبُ وَهُوَ يَقُولُ ”أَنْذَرْتُكُمُ النَّارَ“ فَلَوْ أَنَّ رَجُلًا مَوْضِعَ كَذَا وَكَذَا سَمِعَ صَوْتَهُ
Simak bin Harb says: I heard Sayyiduna Nu'man bin Bashir (may Allah be pleased with him) giving a sermon, and he had draped a sheet over himself. He said: I heard the Messenger of Allah (peace and blessings be upon him) say during a sermon: I have warned you about Hell. The Messenger of Allah (peace and blessings be upon him) said this in such a loud voice that if a person had been at such-and-such place, he would have heard it as well.
