2ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ سَلَمَةَ بْنِ الْخَطَّابِ عَنْ عَلِيِّ بْنِ سَيْفِ بْنِ عَمِيرَةَ عَنْ أَبِيهِ عَنْ عُمَرَ بْنِ حَنْظَلَةَ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ إِذَا زَالَتِ الشَّمْسُ دَخَلَ وَقْتُ الظُّهْرِ إِلاَّ أَنَّ بَيْنَ يَدَيْهَا سُبْحَةً وَذَلِكَ إِلَيْكَ إِنْ شِئْتَ طَوَّلْتَ وَإِنْ شِئْتَ قَصَّرْتَ.
2. Muhammad ibn Yahya has narrated from Salmah ibn af-Khattab from Ali ibn Sayf ibn ‘Amirah from his father form ‘Umar ibn Hanzalah who has said the following: “Abu ‘Abd Allah 
, has said, ‘When the sun declines toward the west at noontime, it is time for al-Dhuhr Salah (prayer) except that there is Nafl (optional Salah (prayer) before al-Dhuhr Salah (prayer). It is up to you to spend a longer time for it or a short one.’”
