3. Muhammad ibn abu ‘Abd Allah has narrated from Muhammad ibn Hassan from al-Hassan ibn al-Husayn from Ali ibn ‘Abd Allah from Yazid ibn Ishaq from Harun ibn Kharijah from al-Mufaddal who has said the following
“Abu Ja‘far (a.s.), has said, ‘On Friday no other form of obedience to Allah is more beloved to me than saying, “Allahumma Salli ‘Ala Muhammad wa ‘Ali Muhammad (O Allah grant Muhammad and his family compensation worthy of their serving Your cause.)””’
