´It was narrated that Ibn 'Abbas said:` "Nabidh of raisins would be made for the Messenger of Allah [SAW] at night, and he would put it in a water skin and drink it during the next day, the day after, and the day after that. At the end of the third day, he would give it to others to drink, or drink it himself, and if anything was left the following morning, he would pour it away."
Explanation & Benefits
Hafiz Muhammad Ameen
English Translation:
If dried grapes (munqqa) are soaked in water at night, by daytime it becomes nabidh. Before this, the fruit remains separate and the water remains separate. During the day, the dried grapes are mixed with water and then squeezed through a cloth to prepare nabidh; therefore, the first night will not be counted. After that, it would be kept and drunk for a further two days and two nights. When the third night began, either it would be consumed, or if any remained, it would be discarded. Thus, in total, it can be drunk for three days and two nights.
