Narrated Anas bin Malik:

that Ar-Rubai' bint An-Nadr came to the Prophet ﷺ - and her son Harithah bin Suraqah had been killed on the Day of Badr, having been struck by an arrow, shot by an unknown person - so she came to the Messenger of Allah ﷺ and said: "Inform me about Harithah. If he has reached goodness, I shall be forbearing and patient. If he has not reached goodness, I will struggle supplicating for him." So Allah's Prophet ﷺ said: "O Umm Harithah! There are gardens in Paradise, and verily your son Harithah has reached the highest part of Paradise, and Al-Firdaws is the highest part of Paradise, its most center and best."

حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، رضى الله عنه أَنَّ الرُّبَيِّعَ بِنْتَ النَّضْرِ، أَتَتِ النَّبِيَّ ﷺ وَكَانَ ابْنُهَا حَارِثَةُ بْنُ سُرَاقَةَ أُصِيبَ يَوْمَ بَدْرٍ أَصَابَهُ سَهْمٌ غَرَبٌ فَأَتَتْ رَسُولَ اللَّهِ ﷺ فَقَالَتْ أَخْبِرْنِي عَنْ حَارِثَةَ لَئِنْ كَانَ أَصَابَ خَيْرًا احْتَسَبْتُ وَصَبَرْتُ وَإِنْ لَمْ يُصِبِ الْخَيْرَ اجْتَهَدْتُ فِي الدُّعَاءِ . فَقَالَ النَّبِيُّ ﷺ " يَا أُمَّ حَارِثَةَ إِنَّهَا جِنَانٌ فِي جَنَّةٍ وَإِنَّ ابْنَكِ أَصَابَ الْفِرْدَوْسَ الأَعْلَى وَالْفِرْدَوْسُ رَبْوَةُ الْجَنَّةِ وَأَوْسَطُهَا وَأَفْضَلُهَا " . قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ مِنْ حَدِيثِ أَنَسٍ .
