Ibn 'Abbas (RAA) narrated, 'Raisins used to be soaked for the Messenger of Allah (ﷺ) in a water skin, and he would drink it that day, the next day and the following day. When it was the evening of the third day, he would drink it and give some to others. If anything was left from it, he would spill it.' Related by Muslim.

وَعَنْ اِبْنِ عَبَّاسٍ رَضِيَ اَللَّهُ عَنْهُمَا قَالَ: { كَانَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-يُنْبَذُ لَهُ اَلزَّبِيبُ فِي اَلسِّقَاءِ, فَيَشْرَبُهُ يَوْمَهُ, وَالْغَدَ, وَبَعْدَ اَلْغَدِ, فَإِذَا كَانَ مَسَاءُ اَلثَّالِثَةِ شَرِبَهُ وَسَقَاهُ, فَإِنْ فَضَلَ شَيْءٌ أَهْرَاقَهُ } أَخْرَجَهُ مُسْلِم ٌ [1]‏ .‏
