Riyad as-Salihin 1148
Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said, "If anyone performs Wudu' properly, then comes to the Friday prayer, listens to the Khutbah (religious talk) attentively and keeps silent, his (minor) sins between that Friday and the following Friday will be forgiven, with the addition of three more days; but he who touches pebbles has caused an interruption. " [Muslim] .

"‏من توضأ فأحسن الوضوء ثم أتي الجمعة، فاستمع وأنصت، غفر له ما بينه وبين الجمعة وزيادة ثلاثة أيام، ومن مس الحصى،  فقد لغا‏"‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏
