Sunan an-Nasai
حَدَّثَنِي مُحَمَّدُ بْنُ إِسْمَاعِيلَ بْنِ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا يَزِيدُ، قَالَ أَنْبَأَنَا هُشَيْمٌ، قَالَ حَدَّثَنَا سَيَّارٌ أَبُو الْحَكَمِ، عَنْ جَبْرِ بْنِ عَبِيدَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ وَعَدَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم غَزْوَةَ الْهِنْدِ فَإِنْ أَدْرَكْتُهَا أُنْفِقْ فِيهَا نَفْسِي وَمَالِي وَإِنْ قُتِلْتُ كُنْتُ أَفْضَلَ الشُّهَدَاءِ وَإِنْ رَجَعْتُ فَأَنَا أَبُو هُرَيْرَةَ الْمُحَرَّرُ .
It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) promised that we would invade India. If I live to see that I will sacrifice myself and my wealth. If I am killed, I will be one of the best of the martyrs, and if I come back, I will be Abu Hurairah Al-Muharrar."
