650. hadíth
وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «أَوَّلُ اَلْوَقْتِ زَوَالُ اَلشَّمْسِ وَ هُوَ وَقْتُ اَللَّهِ اَلْأَوَّلُ وَ هُوَ أَفْضَلُهُمَا.
Imam Jafar ibn Muhammad Al-Sadiq (a.s) said: "The beginning of the time (for Dhuhr prayer) is at the sun's decline (from its zenith), and it is the initial time decreed by Allah (swt), and it is the best of them."
