Um Ar-Rubai'bint Al-Bara', the mother of Hartha bin Suraqa came to the Prophet ﷺ and said, "O Allah's Prophet! Will you tell me about Hartha?" Hartha has been killed (i.e. martyred) on the day of Badr with an arrow thrown by an unidentified person. She added, "If he is in Paradise, I will be patient; otherwise, I will weep bitterly for him." He said, "O mother of Hartha! There are Gardens in Paradise and your son got the Firdausal-ala (i.e. the best place in Paradise). (Using translation from Bukhārī 2809)   

أَنَّ أُمَّ الرُّبَيِّعِ بِنْتَ الْبَرَاءِ وَهِيَ أُمُّ حَارِثَةَ بِنْتُ سُرَاقَةَ أَتَتِ النَّبِيَّ ﷺ فَقَالَتْ يَا نَبِيَّ اللهِ أَلَا تُخْبِرُنِي عَنْ حَارِثَةَ؟ وَكَانَ قُتِلَ يَوْمَ بَدْرٍ أَصَابَهُ سَهْمٌ غَرْبٌ فَإِنْ كَانَ فِي الْجَنَّةِ صَبَرْتُ وَإِنْ كَانَ غَيْرَ ذَلِكَ اجْتَهَدْتُ عَلَيْهِ الْبُكَاءَ قَالَ يَا أُمَّ حَارِثَةَ إِنَّهَا جِنَانٌ فِي الْجَنَّةِ وَإِنَّ ابْنَكِ أَصَابَ الْفِرْدَوْسَ الْأَعْلَى قَالَ قَتَادَةُ الْفِرْدَوْسُ رَبْوَةٌ فِي الْجَنَّةِ وَأَوْسَطُهَا وَأَفْضَلُهَا
