عَنْ أَبِي هَمَّامٍ الشَّعْبَانِيِّ قَالَ حَدَّثَنِي رَجُلٌ مِنْ خَثْعَمَ قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فِي غَزْوَةِ تَبُوكَ فَوَقَفَ ذَاتَ لَيْلَةٍ وَاجْتَمَعَ عَلَيْهِ أَصْحَابُهُ فَقَالَ إِنَّ اللَّهَ أَعْطَانِي اللَّيْلَةَ الْكَنْزَيْنِ كَنْزَ فَارِسَ وَالرُّومِ وَأَمَدَّنِي بِالْمُلُوكِ مُلُوكِ حِمْيَرَ الْأَحْمَرَيْنِ وَلَا مُلْكَ إِلَّا لِلَّهِ يَأْتُونَ يَأْخُذُونَ مِنْ مَالِ اللَّهِ وَيُقَاتِلُونَ فِي سَبِيلِ اللَّهِ قَالَهَا ثَلَاثًا
It is narrated from Abu Hammam Shabani, who says: A man from Banu Khath'am related to me that we were with the Messenger of Allah, peace and blessings be upon him, in the Battle of Tabuk. The Prophet, peace and blessings be upon him, stood in prayer at night, and the noble companions gathered near him. The Prophet, peace and blessings be upon him, said: Allah Almighty has granted me tonight the two treasures of Persia and Rome, and has helped me through the red-colored kings of Himyar. Indeed, sovereignty belongs only to Allah Almighty. These kings will come and, taking Allah's wealth, will strive in the way of Allah. The Prophet, peace and blessings be upon him, said this three times.
