Chapter 7 | The Time of Morning Salah (Prayer)
5ـ عَلِيٌّ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ وَقْتُ الْفَجْرِ حِينَ يَنْشَقُّ الْفَجْرُ إِلَى أَنْ يَتَجَلَّلَ الصُّبْحُ السَّمَاءَ وَلاَ يَنْبَغِي تَأْخِيرُ ذَلِكَ عَمْداً لَكِنَّهُ وَقْتٌ لِمَنْ شُغِلَ أَوْ نَسِيَ أَوْ نَامَ.
5. Ali has narrated from his father Ibn Abi ‘Umayr from Hammad al-Halabiy who has said the following: “Abu ‘Abd Allah , has said, ‘The time for morning Salah (prayer) begins when dawn opens, until morning (with rays) brightens the sky. It is not proper to delay purposely; however, there is time for those who are preoccupied, forget or are sleeping.”
