I was under the guardianship of Ibn Umar. Raisins would be soaked for him, and he would drink the infusion the next day. Then the raisins would be dried, more raisins would be added to them, water would be poured over them, and he would drink it the following day. When the day after that came, he would throw it out.They cited as evidence the hadith of Abu Masud Uqba bin Amr.
أخبرنا سويد قال أنبأنا عبد الله عن عبيد الله بن عمر السعيدي قال
كنت في حجر ابن عمر فكان ينقع له الزبيب فيشربه من الغد ثم يجفف الزبيب ويلقى عليه زبيب آخر ويجعل فيه ماء فيشربه من الغد حتى إذا كان بعد الغد طرحه واحتجوا بحديث أبي مسعود عقبة بن عمرو
[Its chain is daif] and it is in al-Kubra, hadith 5211 * Ruqayya is unknown (mastura), and Ubaydullah al-Basri is of unknown status, Abdullah is Ibn Mubarak.
