The Purse
Scholars have said that opening a purse may indicate revealing the secret entrusted within it. It was also said that the 'qirbah' (waterskin) symbolizes a trustworthy old woman entrusted with money, and the 'qarurah' or 'qininah' (bottle/flask) may symbolize a slave girl, a boy, or a woman, citing a noble prophetic hadith.
