this statement of Allah: “And do not consume their wealth along with your own wealth” [al-Nisa’ 4:2]—that is, together with your own wealth. However, this analogy is open to question, for the verse concerns property and is not comparable to the verse on washing. Allah says: “Give the orphans their property; do not exchange the inferior for the good, and do not consume their property along with your own” [al-Nisa’ 4:2]. That is, when it has been joined to your own property; for a person does not consume another’s wealth unless he has incorporated it into his own. Thus, the words, “Do not consume,” carry the sense of joining.
The verse on ablution, however, is not like this.
The correct answer is that the endpoint is included, as established by the sunnah. Abu Hurayrah, may Allah be pleased with him, performed ablution until he washed up into his upper arm, and said, “This is how I saw the Prophet ﷺ do it.” (1) This indicates that the elbow is included.
It is also reported that he ﷺ performed ablution and passed water around his elbows. (2)
It may be said that the endpoint is not included when the beginning of the limit is expressly mentioned with “from”; but when it is not mentioned, the endpoint is included. Thus, if someone were to ask: Which is better when washing the hands: to begin at the elbow, the middle of the forearm, or the fingertips?
The answer would be that it is better to begin at the fingertips, due to the word “up to,” although this does not seem strongly evident to me, because the starting point
