Sahih al-Bukhari, Hadith 6550 ⓘ

Narrated Anas: Haritha was martyred on the day (of the battle) of Badr while he was young. His mother came to the Prophet saying, "O Allah's Messenger! You know the relation of Haritha to me (how fond of him I was); so, if he is in Paradise, I will remain patient and wish for Allah's reward, but if he is not there, then you will see what I will do." The Prophet replied, "May Allah be merciful upon you! Have you gone mad? (Do you think) it is one Paradise? There are many Paradises and he is in the (most superior) Paradise of Al-Firdaus."

حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا مُعَاوِيَةُ بْنُ عَمْرٍو، حَدَّثَنَا أَبُو إِسْحَاقَ، عَنْ حُمَيْدٍ، قَالَ سَمِعْتُ أَنَسًا، يَقُولُ أُصِيبَ حَارِثَةُ يَوْمَ بَدْرٍ وَهْوَ غُلاَمٌ، فَجَاءَتْ أُمُّهُ إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَتْ يَا رَسُولَ اللَّهِ قَدْ عَرَفْتَ مَنْزِلَةَ حَارِثَةَ مِنِّي، فَإِنْ يَكُ فِي الْجَنَّةِ أَصْبِرْ وَأَحْتَسِبْ، وَإِنْ تَكُنِ الأُخْرَى تَرَى مَا أَصْنَعُ‏.‏ فَقَالَ ‏ "‏ وَيْحَكِ ـ أَوَهَبِلْتِ ـ أَوَجَنَّةٌ وَاحِدَةٌ هِيَ جِنَانٌ كَثِيرَةٌ، وَإِنَّهُ لَفِي جَنَّةِ الْفِرْدَوْسِ ‏" ‏‏.‏
