The Messenger of Allah (may Allah bless him and grant him peace) said:
“Confer Salaat (prayers) increasingly upon me during the day of Jumua and during the eve of Jumua*. Whosoever does so, I will be his witness or I will intercede for him on the Day of Judgement.”
[Related by Al-Bayhaqi]
*Eve of Jumua is Thursday nights after Salatul Maghrib
Was Salam
