It is narrated from Abu Rashid al-Hubrani that he said: I met the horseman of the Messenger of Allah (peace and blessings be upon him), Sayyiduna al-Miqdad bin al-Aswad (may Allah be pleased with him), sitting on one of the large chests of the money-changers, and he was overflowing from it because of his heavy build. He intended to go on a military expedition. I said (seeing his infirmity): "Allah has excused you (from staying behind from jihad)." He said: "Surah al-Buhuth (that is, Surah al-Tawbah) has made (staying behind) hard for me. Allah, the Mighty and Majestic, says: 'Go forth, whether light or heavy.' [Surah al-Tawbah: 41] ." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
