Hadith Footnote:
Jarba and Azraja are two villages in the land of Sham (Greater Syria) between which there is a distance of three days’ journey.
In one hadith it is mentioned that my reservoir (hawd) is the distance of a month’s journey.
In another hadith it is stated that it is as far as the distance between Aylah and Sana’a.
In a third hadith it is mentioned that it is as far as the distance between Madinah and Sana’a.
In a fourth hadith it is stated that it is as far as the distance from Aylah to Aden.
In a fifth hadith it is mentioned that it is as far as the distance from Aylah to Juhfah.
All of these were said by the Prophet (sallallahu alayhi wa sallam) approximately to make it understandable for the people, mentioning those locations which they recognized.
It is possible that in some narrations the length is mentioned, and in others the width.
Qastallani said that all these locations are approximately at the same distance, that is, about half a month’s journey or slightly more.

It is possible that in some hadiths the length of the reservoir is mentioned, and in others its width.
All these locations are approximately at the same distance, that is, about half a month’s journey or a little more or less than that. Furthermore, the distance can also vary depending on whether the mount is fast or slow.
(Fath al-Bari: 11/574)
Some people, in view of these differences, have denied the very existence of the Hawd al-Kawthar, even though there are so many authentic hadiths on this subject that they reach the level of tawatur (mass transmission).
And Allah knows best.

Benefits and Issues:
Islamic teachings are based on moderation and balance, steering away from excess. In these teachings, every individual is commanded to fulfill their duties correctly and responsibly, because if every person fulfills their own obligation, then the rights of others will automatically be fulfilled. Therefore, instead of demanding rights, emphasis has been placed on the fulfillment of duties. Here, the wealthy are advised to receive those who come to collect zakat with cheerfulness and not to show reluctance or make excuses in the payment of zakat, and to send them back happily. Elsewhere, the Prophet (sallallahu alayhi wa sallam) has given appropriate instructions to those who collect charity, so that they do not oppress or wrong people.
