When this verse was revealed:" And warn thy nearest kindred," the Messenger of Allah ﷺ set off towards a rock of the hill and ascended the highest of the rocks and then called: 0 sons of 'Abd Manaf! I am a warner; my similitude and your similitude is like a man who saw the enemy and went to guard his people, but, being afraid they might get there before him, he shouted: Be on your guard!  

انْطَلَقَ نَبِيُّ اللَّهِ ﷺ إِلَى رَضْمَةٍ مِنْ جَبَلٍ فَعَلاَ أَعْلاَهَا حَجَرًا ثُمَّ نَادَى يَا بَنِي عَبْدِ مَنَافَاهْ إِنِّي نَذِيرٌ إِنَّمَا مَثَلِي وَمَثَلُكُمْ كَمَثَلِ رَجُلٍ رَأَى الْعَدُوَّ فَانْطَلَقَ يَرْبَأُ أَهْلَهُ فَخَشِيَ أَنْ يَسْبِقُوهُ فَجَعَلَ يَهْتِفُ يَا صَبَاحَاهْ  

[Machine] And about Qabeesa ibn Makhariq al-Hilali, he said: When this verse was revealed to the Prophet ﷺ {And warn your closest kindred}, the Prophet of Allah ﷺ went to a mount called Rakhma, climbed to its summit, and said, "O sons of Abd Manaf, I am a warner. My example and your example is like that of a man who sees the enemy coming and hurries to his family to protect them, fearing that they might be harmed. He then calls out, 'O my companions, O my companions, you have been attacked, you have been attacked.'"  

وَعَنْ قَبِيصَةَ بْنِ مُخَارِقٍ الْهِلَالِيِّ قَالَا لَمَّا نَزَلَتْ عَلَى النَّبِيِّ ﷺ هَذِهِ الْآيَةُ {وَأَنْذِرْ عَشِيرَتَكَ الْأَقْرَبِينَ} انْطَلَقَ نَبِيُّ اللهِ ﷺ إِلَى رَخْمَةٍ مِنْ جَبَلٍ فَعَلَا أَعْلَاهَا حَجَرًا ثُمَّ قَالَ يَا بَنِي عَبْدِ مَنَافٍ إِنِّي نَذِيرٌ إِنَّمَا مَثَلِي وَمَثَلُكُم كَمَثَلِ رَجُلٍ رَأَى الْعَدُوَّ فَانْطَلَقَ يَرْبَأُ أَهْلَهُ فَخَشِيَ أَنْ يَسْبِقُوهُ إِلَى أَهْلِهِ فَجَعَلَ يَهْتِفُ يَا صَاحِبَاهُ يَا صَاحِبَاهُ أُتِيْتُمْ أُتِيْتُمْ
