Ali ibn Muhammad ibn Bandar has narrated from Ahmad ibn abu ‘Abd Allah, from abu Sulayman, from Ahmad ibn al-Hassan al- Jabaliy (al-Halabiy), from his father, from Jamil ibn Darraj who has said the following: “I once heard abu ‘Abd Allah (a.s.), saying, ‘If one does not take dinner one Saturday and Sunday nights consecutively, his strength will go away and will not come back until forty days later.’” جهول - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (2/101))
