The Prophet ﷺ said: If anyone omits the Friday prayer without excuse, he must give a dinar in alms, or if he does not have as much, then half a dinar. Abu Dawud said: Khalid b. Qais reported this tradition in this manner, but he disagreed in respect of chain (of transmitters) and agreed in respect of the text. (Using translation from Abū Dāʾūd 1053)
عَنِ النَّبِيِّ ﷺ قَالَ مَنْ تَرَكَ الْجُمُعَةَ مِنْ غَيْرِ عُذْرٍ فَلْيَتَصَدَّقْ بِدِينَارٍ فَإِنْ لَمْ يَجِدْ فَنِصْفِ دِينَارٍ
