Bukhari

Hadith Footnote:
Sa’d bin Mu’adh al-Ansari al-Ashhali was from the Aws tribe. In Medina, he was present between the First and Second Aqabah pledges.

Hadith Commentary: The indication of the Prophet (sallallahu alayhi wa sallam) was that even the greatest of worldly blessings does not possess more value or worth than the handkerchief with which a person of Paradise wipes his nose and mouth.

Hadith Commentary:
A handkerchief is considered to have a very low status among garments, because it is used to clean the hands or to remove dust from the face. In Paradise, even this lowly piece of cloth will have such a status that, in comparison to it, the greatest of worldly blessings will hold no value whatsoever.
When this is the worth and value of a mere inferior cloth,
then the beauty and adornment of the finest and most superior garments of Paradise is certainly beyond our imagination.

Hadith Commentary:
(1)
In the presence of the Messenger of Allah (sallallahu alayhi wa sallam), the noble Companions (radi Allahu anhum) touched the silk cloth and expressed their amazement at its softness. The Messenger of Allah (sallallahu alayhi wa sallam) did not comment on their touching it; rather, he responded to their amazement. From this, Imam Bukhari (rahimahullah) has established that wearing silk is forbidden, but touching it is permissible.

(2)
Sa’d bin Mu’adh (radi Allahu anhu) was the chief of the Ansar, which is why the Prophet (sallallahu alayhi wa sallam) made special mention of him, because those who touched the silk cloth and expressed their amazement and wonder at it were the Ansar. The Messenger of Allah (sallallahu alayhi wa sallam) mentioned only the handkerchief, because it is generally used to wipe sweat and hands, and it is not regarded with respect. When the handkerchief of Sa’d bin Mu’adh (radi Allahu anhu) is praiseworthy, then, by greater reason, any other garment of Paradise will be even more worthy of praise.

Explanation:
1:
In other words, the Prophet (sallallahu alayhi wa sallam) gave the glad tidings of Sa'd bin Mu'adh (radi Allahu anhu) being among the people of Paradise while still in this world.

Commentary:
(1)
From this it is understood that Sa’d bin Mu’adh radi Allahu anhu is not only among the people of Paradise, but he will also be granted the highest blessings of Paradise.

(2)
Among the blessings of Paradise are all kinds of garments, even handkerchiefs.

(3)
Even the most precious thing in this world cannot compare to even the most ordinary thing in Paradise.

(4)
A gift should be accepted, even if it is from a polytheist.
It should be noted that this gift was a cloak (quba) which the brother of the governor of Dumat al-Jandal sent to the service of the Prophet sallallahu alayhi wa sallam.

(5)
Sa’d bin Mu’adh radi Allahu anhu was an Ansari Companion.
He was the chief of the Aws tribe.
He had the honor of participating in the Battle of Badr, and in the Battle of Khandaq he was struck by an arrow, from which he attained martyrdom.
