2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ibn Abi ‘Umayr Hisham ibn Salim from Muhammad ibn Muslim who has said the following: “Abu Ja‘far , has said, ‘Of Salah (prayer) of a servant (of Allah) sometimes one-half, sometimes one-third, one-fourth or one-fifth is raised. Whatever is raised is only what one has performed with love from his heart. We only command to perform optional Salah (prayer) to complete what it is cut short of obligatory ones.’”
