tirmidhi:3128ʿAbd b. Ḥumayd > ʿAlī b. ʿĀṣim > Yaḥyá al-Bakkāʾ > ʿAbdullāh b. ʿUmar > ʿUmar b. al-Khaṭṭāb

"I heard 'Umar bin Al-Khattab saying: 'The Messenger of Allah ﷺ said: "Four before Zuhr, after the zenith, are reckoned with their like from Salat As-Sahr (meaning the reward is like that of the two Sunan and obligatory Rak'ah of Fajr)." The Messenger of Allah ﷺ said: "There is nothing but that it glorifies Allah at that hour." Then he recited the Ayah: Their shadows shift from right to left, prostrating to Allah while they are humble (16:48).  

الترمذي:٣١٢٨حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ حَدَّثَنَا عَلِيُّ بْنُ عَاصِمٍ عَنْ يَحْيَى الْبَكَّاءِ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ عُمَرَ قَالَ سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ يَقُولُ

قَالَ رَسُولُ اللَّهِ ﷺ أَرْبَعٌ قَبْلَ الظُّهْرِ بَعْدَ الزَّوَالِ تُحْسَبُ بِمِثْلِهِنَّ فِي صَلاَةِ السَّحَرِ قَالَ رَسُولُ اللَّهِ ﷺ وَلَيْسَ مِنْ شَيْءٍ إِلاَّ وَهُوَ يُسَبِّحُ اللَّهَ تِلْكَ السَّاعَةَ ثُمَّ قَرَأَ ( يَتَفَيَّأُ ظِلاَلُهُ عَنِ الْيَمِينِ وَالشَّمَائِلِ سُجَّدًا لِلَّهِ ) الآيَةَ كُلَّهَا  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ غَرِيبٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ عَلِيِّ بْنِ عَاصِمٍ
