Mishkat al-Masabih 19 Jihad كتاب الجهاد 23

وَعَن أنسٍ أَنَّ الرُّبَيِّعَ بِنْتَ الْبَرَاءِ وَهِيَ أَمُّ حَارِثَةَ بْنِ سُرَاقَةَ أَتَتِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَتْ: يَا رَسُولَ اللَّهِ أَلَا تُحَدِّثُنِي عنْ حَارِثَةَ وَكَانَ قُتِلَ يَوْمَ بَدْرٍ أَصَابَهُ سَهْمٌ غَرْبٌ فَإِنْ كَانَ فِي الْجَنَّةِ صَبَرْتُ وَإِنْ كَانَ غَيْرُ ذَلِكَ اجْتَهَدْتُ عَلَيْهِ فِي الْبُكَاءِ فَقَالَ: «يَا أَمَّ حَارِثَةَ إِنَّهَا جِنَانٌ فِي الْجَنَّةِ وَإِنَّ ابْنَكِ أَصَابَ الْفِرْدَوْسَ الْأَعْلَى» . رَوَاهُ البخاريُّ

Anas told that ar-Rubaiyi‘ daughter of al-Bara’, who was the mother of Haritha b. Suraqa, came to the Prophet and said, “Prophet of God, will you not tell me about Haritha? (He had been killed at the battle of Badr, being struck by a random arrow.) If he is in paradise I shall show endurance, but if he has met another fate I shall exert myself in weeping for him.” He replied, “Mother of Haritha, in paradise there are gardens, and your son has attained to al-Firdaus, the highest.” Bukhari transmitted it.
