Muhammad Bin Yahya, from Salama Bin Al Khattab, from Ali Bin Sayf Bin Ameyra, from his father, from Umar Bin Hanzala, (It has been narrated) from Abu Abdullah -asws having said: ‘When the sun (starts to) decline the time of Al-Al-Zohr enters except if there is Optional ( Salāt ) in front of it, and that is up to you. If you so desire to, prolong, and if you so desire to, shorten’.
[25] عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ صَالِحِ بْنِ سَعِيدٍ عَنْ يُونُسَ عَنْ بَعْضِ رِجَالِهِ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ سَأَلْتُهُ عَمَّا جَاءَ فِي الْحَدِيثِ أَنْ صَلِّ الظُّهْرَ إِذَا كَانَتِ الشَّمْسُ قَامَةً وَ قَامَتَيْنِ وَ ذِرَاعاً وَ ذِرَاعَيْنِ وَ قَدَماً وَ قَدَمَيْنِ مِنْ هَذَا وَ مِنْ هَذَا فَمَتَى هَذَا وَ كَيْفَ هَذَا وَ قَدْ يَكُونُ الظِّلُّ فِي بَعْضِ الْأَوْقَاتِ نِصْفَ قَدَمٍ قَالَ إِنَّمَا قَالَ ظِلُّ الْقَامَةِ وَ لَمْ يَقُلْ قَامَةُ الظِّلِّ وَ ذَلِكَ أَنَّ ظِلَّ الْقَامَةِ يَخْتَلِفُ مَرَّةً يَكْثُرُ وَ مَرَّةً يَقِلُّ وَ الْقَامَةُ قَامَةٌ أَبَداً لَا يَخْتَلِفُ Ali Bin Ibrahim, from his father, from Salih Bin Saeed, from Yunus, from one of his men, (It has been narrated) from Abu Abdullah -asws , said, ‘I asked him -asws about what has come in the Hadeeth that Al-Al-Zohr would be prayed when the sun was one upright (in length of shadow) and two, and one cubit and two, and one step and two, from this and from there.
So when is this? And how is this, and the shadow happens to be, at certain times, half a step?’ He -asws said: ‘But rather, the shadow is referred to as one shadow upright and is not said as ‘uprightness of the shadow’, and that is (because) one shadow upright differs sometimes as more, and sometimes as less, and the upright (object) would be of one uprightness (size) for ever, not being different’.
