اَلسَّلَامُ عَلَيْكُمْ ustadh, Is increasing in salawaat on Friday an authentic practice? جزاك الله خيراً

‎Yes. The Prophet ﷺ‎ said “Increase your salah upon me on Friday, for your salah is presented to me” (Abu Dawud, graded sahih by al-Albani). The scholars said this is prescribed throughout Friday, without fixing a number or an hour, and without gathering to say it together aloud.
