Muhammad ibn Ya‘qub from al-Husayn ibn Muhammad from Abdullah ibn ‘Amir from Ali ibn Mahziyar from Fadalah ibn Ayyub from Abd al-Rahman ibn Abi Abdillah: Abu Abdillah عليه السلام said: "If you prayed while not facing the Qiblah, and it becomes clear to you that you prayed not facing the Qiblah while you are still within the time, then repeat it. But if the time has passed, then do not repeat it."
