“When Qasim the son of the Messenger of Allah ﷺ died, Khadijah said: ‘O Messenger of Allah, the milk of Qasim’s mother is overflowing. Would that Allah had let him live until he had finished breastfeeding.’ The Messenger of Allah ﷺ said: ‘He will complete his breastfeeding in Paradise.’ She said: ‘If I know that, O Messenger of Allah, it makes it easier for me to bear.’ The Messenger of Allah ﷺ said: ‘If you wish, I will pray to Allah to let you hear his voice.’ She said: ‘O Messenger of Allah, rather I believe Allah and His Messenger.’”
لَمَّا تُوُفِّيَ الْقَاسِمُ ابْنُ رَسُولِ اللَّهِ ﷺ قَالَتْ خَدِيجَةُ يَا رَسُولَ اللَّهِ دَرَّتْ لُبَيْنَةُ الْقَاسِمِ فَلَوْ كَانَ اللَّهُ أَبْقَاهُ حَتَّى يَسْتَكْمِلَ رَضَاعَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّ تَمَامَ رَضَاعِهِ فِي الْجَنَّةِ قَالَتْ لَوْ أَعْلَمُ ذَلِكَ يَا رَسُولَ اللَّهِ لَهَوَّنَ عَلَىَّ أَمْرَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنْ شِئْتِ دَعَوْتُ اللَّهَ تَعَالَى فَأَسْمَعَكِ صَوْتَهُ قَالَتْ يَا رَسُولَ اللَّهِ بَلْ أُصَدِّقُ اللَّهَ وَرَسُولَهُ
