[Machine] I went to Al-Miqdad ibn Al-Aswad, the horseman of the Messenger of Allah ﷺ , while he was sitting on a tomb made of "Sayyara" (a type of stone), and he was separating bones from it while intending to go for battle. I said, "May Allah forgive you." He replied, "Come to the Surah of Al-Buhuth." Allah Almighty said, "March forth lightly or heavily" [Surah At-Tawbah 9:41], meaning the Surah of At-Tawbah. "This is a correct narration, and they did not deny it."  

وَافَيْتُ الْمِقْدَادَ بْنَ الْأَسْوَدِ فَارِسَ رَسُولِ اللَّهِ ﷺ جَالِسًا عَلَى تَابُوتٍ مِنْ تَوَابِيتِ الصَّيَارِفَةِ وَفَصَلَ عَنْهَا عَظْمًا وَهُوَ يُرِيدُ الْغَزْوَ فَقُلْتُ لَقَدْ أَعْذَرَ اللَّهُ إِلَيْكَ فَقَالَ ائْتِ عَلَى سُورَةِ الْبُحُوثِ قَالَ اللَّهُ ﷻ {انْفِرُوا خِفَافًا وَثِقَالًا} [التوبة 41] يَعْنِي سُورَةَ التَّوْبَةِ «هَذَا صَحِيحُ الْإِسْنَادِ وَلَمْ يُخَرِّجَاهُ» صحيح  

[Machine] I saw Al-Miqdad, the warrior of the Messenger of Allah ﷺ, sitting on a coffin made of sailboat wood in Hims, which was superior to it in quality. He intended to go on a military expedition, so I said, "May Allah excuse you." He said, "The verse of Al-Ba'athah has not been revealed to us yet: 'And prepare against them whatever you are able of power and of steeds of war by which you may terrify the enemy of Allah and your enemy and others besides them whom you do not know [but] whom Allah knows.'"  

رَأَيْتُ الْمِقْدَادَ فَارِسَ رَسُولِ اللهِ ﷺ جَالِسًا عَلَى تَابُوتٍ مِنْ تَوَابِيتِ الصَّيَارِفَةِ بِحِمْصَ قَدْ أَفْضَلَ عَنْهَا مِنْ عَظْمِهِ يُرِيدُ الْغَزْوَ فَقُلْتُ لَقَدْ أَعْذَرَ اللهُ إِلَيْكَ قَالَ أَبَتْ عَلَيْنَا سُورَةُ الْبَعُوثِ {انْفِرُوا خِفَافًا وَثِقَالًا}
