Al-Husayn ibn Muhammad al-Ash’ariy has narrated from ‘Abd Allah ibn ‘Amir from Ali ibn Mahziyar from Fadalah ibn Ayyub from Hammad ibn ‘Uthaman who has said the following: “I once asked him (the Imam) (a.s.), about optional Salah (prayer) during the day. He (the Imam) said, ‘He performs eight Rak‘at before al-Dhuhr and eight after al-Dhuhr.’” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (15/400))
