عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ وَعَدَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فِي غَزْوَةِ الْهِنْدِ فَإِنِ اسْتُشْهِدْتُ كُنْتُ مِنْ خَيْرِ الشُّهَدَاءِ وَإِنْ رَجَعْتُ فَأَنَا أَبُو هُرَيْرَةَ الْمُحَرَّرُ
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), he says: The Messenger of Allah (peace and blessings be upon him) promised us the battle of India. If I am martyred in it, then I will be the best of martyrs, and if I return from it, then Abu Hurairah will return freed from the Fire.
