Anas (May Allah be pleased with him) reported:
Umm Ar-Rubaiy'i bint Al-Bara', who was the mother of Harithah bin Suraqah, came to the Prophet (ﷺ) and said: "O Messenger of Allah! Will you not tell me about Harithah? (He was killed in the battle of Badr). If he is in Jannah I shall show endurance, but if he has met another fate, I may exert myself in weeping for him." He (ﷺ) replied, "O mother of Harithah, in in the gardens of Jannah there are many ranks, and your son has attained Al-Firdaus, the highest."[Al- Bukhari].
