The Reward of one who seeks Reward for (The loss of) Three of his own Children

It was narrated from Anas that the Messenger of Allah said:

"Whoever seeks reward for (the loss of) three of his own children, he will enter Paradise." A woman stood up and said: "Or two?" He said: "Or two." The woman said: "I wish that I had said, 'or one."'

أَخْبَرَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ، قَالَ حَدَّثَنَا ابْنُ وَهْبٍ، حَدَّثَنِي عَمْرٌو، قَالَ حَدَّثَنِي بُكَيْرُ بْنُ عَبْدِ اللَّهِ، عَنْ عِمْرَانَ بْنِ نَافِعٍ، عَنْ حَفْصِ بْنِ عُبَيْدِ اللَّهِ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " مَنِ احْتَسَبَ ثَلاَثَةً مِنْ صُلْبِهِ دَخَلَ الْجَنَّةَ " . فَقَامَتِ امْرَأَةٌ فَقَالَتْ أَوِ اثْنَانِ قَالَ " أَوِ اثْنَانِ " . قَالَتِ الْمَرْأَةُ يَا لَيْتَنِي قُلْتُ وَاحِدًا .
