Tirmidhi

1:
The narrator is in doubt whether you said "khamosh" or "khadoosh" or "kadooh"—all of which approximately mean "scratch."
Some scholars, by considering "khadoosh," "khamosh," and "kadooh" as synonyms, attribute the narrator's doubt to this, while others say that these are ranks of wounds: the lowest degree of wound is "kadooh," then "khadoosh," and then "khamosh."

Note:
(In the chain of narration, both Hakim bin Jubair and Sharik al-Qadi are weak narrators,
but due to the corroboration (mutaba‘ah) of Zubayd in the next narration, this hadith is authentic.)

1626. Commentary:
➊ The meaning of (khamosh and khadoosh) is to scratch and injure the face with nails or with something like iron. The meaning of (kadooh) is the wounds and marks that become apparent due to scratching. Biting with teeth is also referred to as (kadooh).
➋ To ask without a legitimate (shar‘i) right is such a grave flaw that a person will be brought forth on the Day of Resurrection humiliated and disgraced before all of creation.
➌ According to the current weight, one dirham is equivalent to 2.975 or 3.06 grams of silver. Based on this, fifty dirhams would be approximately equal to 13 tolahs of silver. Its current value can be ascertained at any time.

Benefits and Issues:
➊
Our esteemed researcher has declared the mentioned narration weak in terms of its chain of transmission, whereas other scholars have considered it hasan (good) due to supporting evidences.
For details, see:
(al-Mawsu‘ah al-Hadithiyyah, Musnad al-Imam Ahmad: 6/195, 196, 197, and al-Sahihah, no. 499).

➋
Even if one possesses a small amount of wealth, one should refrain from asking (begging).

➌
It is not a condition to be a possessor of the nisab (minimum amount liable for zakat) in order for refraining from asking to be obligatory, because the nisab for zakat in silver is two hundred dirhams, whereas the Messenger of Allah (sallallahu alayhi wa sallam) did not permit a person who owns fifty dirhams of silver to ask (beg).

➍
The hadith mentions silver and gold because, at that time, dirhams and dinars were made of silver and gold.
A dirham, according to current weight, is equivalent to 2.975 or 3.06 grams of silver.
Accordingly, fifty dirhams would be approximately equal to 13 tolas (traditional South Asian unit) of silver.
Its current value can always be ascertained.

➎
In some cases, it becomes permissible even for a wealthy person to ask (beg).
These cases will be mentioned in the next chapter.

(1) The aforementioned narration has been declared weak in its chain of transmission by the researcher of the book, whereas other scholars have deemed it hasan (good) on the basis of supporting evidences and corroborating narrations. Therefore, despite the chain of transmission being weak, this narration is actionable due to the supporting evidences and corroborations. And Allah knows best. For details, see: (Al-Mawsu‘ah al-Hadithiyyah, Musnad al-Imam Ahmad: 6/194, 197; al-Sahihah by al-Albani: 1/899, Hadith no. 499)

(2) “Fifty dirhams.” This is approximately equivalent to 5,250 rupees; therefore, it is not permissible for a person who owns this much wealth to ask from people. In some narrations, forty dirhams are mentioned; this depends on the circumstances. And Allah knows best.
