Ruqaiyah bint 'Amr bin Sa'd said:"I was under the care of Ibn 'Umar, and raisins would be soaked for him and he would drink them in the morning, then the raisins would be left to dry, and other raisins would be added to them, and water would be poured on top of them, and he would drink that in the morning. Then the day after he would throw them away."
أَخْبَرَنَا سُوَيْدٌ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ السَّعِيدِيِّ، قَالَ حَدَّثَتْنِي رُقَيَّةُ بِنْتُ عَمْرِو بْنِ سَعِيدٍ، قَالَتْ كُنْتُ فِي حَجْرِ ابْنِ عُمَرَ فَكَانَ يُنْقَعُ لَهُ الزَّبِيبُ فَيَشْرَبُهُ مِنَ الْغَدِ ثُمَّ يُجَفَّفُ الزَّبِيبُ وَيُلْقَى عَلَيْهِ زَبِيبٌ آخَرُ وَيُجْعَلُ فِيهِ مَاءٌ فَيَشْرَبُهُ مِنَ الْغَدِ حَتَّى إِذَا كَانَ بَعْدَ الْغَدِ طَرَحَهُ . وَاحْتَجُّوا بِحَدِيثِ أَبِي مَسْعُودٍ عُقْبَةَ بْنِ عَمْرٍو .
