Tirmidhi

English Commentary:
1:
The meaning of "performed ablution (wudu) well" is that he performed ablution according to the Sunnah.

2:
From this, it is understood that coming to the mosque after performing ablution at home is more virtuous.

3:
That is, the sins of ten days are forgiven, because the reward of one good deed is at least tenfold.

4:
By this, minor sins are meant, because major sins are not forgiven without repentance.

Hadith Commentary: Benefits and Issues: The reward for every good deed is at least tenfold. Therefore, a person who, with great care, performs ritual bath (ghusl), comes early for Jumu‘ah before the sermon, and, to the best of his ability, offers voluntary prayers (nawafil), and when the sermon begins, listens to it attentively and silently—then his minor sins of ten days are forgiven, and the remaining reward is separate.

1050. Commentary:
By "good ablution" (wudu) is meant a complete ablution according to the Sunnah, in which nothing is left incomplete nor is there any extravagance in the use of water.
➋ This forgiveness confirms the blessed verse of the Noble Qur’an:
«مَن جَاءَ بِالْحَسَنَةِ فَلَهُ عَشْرُ أَمْثَالِهَا ۖ وَمَن جَاءَ بِالسَّيِّئَةِ فَلَا يُجْزَىٰ إِلَّا مِثْلَهَا وَهُمْ لَا يُظْلَمُونَ» [الانعام: 160]
Whoever does a good deed, for him is ten times its reward.
➌ This hadith indicates listening to the Friday sermon silently and attentively, and gives glad tidings of such a great reward for adopting this Sunnah manner.

Benefits and Issues:

➊ In the blessed era of the Prophet (sallallahu alayhi wa sallam), the floors of mosques were not paved. Therefore, pebbles would be spread on the ground so that dust would not stick to the clothes.

➋ Touching the pebbles refers to touching them without necessity, which is contrary to proper etiquette. Similarly, playing with the fibers of a mat or becoming preoccupied with anything spread beneath oneself in such a way that attention is diverted from the prayer is inappropriate.

Benefits and Issues:

➊ By fully observing the etiquettes and performing the Friday prayer (Jumu‘ah) properly, the sins of ten days are forgiven.

➋ From such ahadith, one should not assume that after performing a single good deed, there is no longer any need for further good deeds, nor any need to avoid sins. This is because no person knows to what extent his good deed is accepted. Therefore, one should strive to perform as many good deeds as possible.
