3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ بْنِ عَبْدِ الرَّحْمَنِ عَنْ عَبْدِ الله بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ سَمِعْتُهُ يَقُولُ لِكُلِّ صَلاَةٍ وَقْتَانِ وَأَوَّلُ الْوَقْتِ أَفْضَلُهُ وَلَيْسَ لأَحَدٍ أَنْ يَجْعَلَ آخِرَ الْوَقْتَيْنِ وَقْتاً إِلاَّ فِي عُذْرٍ مِنْ غَيْرِ عِلَّةٍ.
3. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus ibn ‘Abd al-Rahman from ‘Abd Allah ibn Sinan who has said the following: “I once heard abu ‘Abd Allah (a.s.), say, ‘For every Salah (prayer) there are two kinds of timings; the beginning of time is the outstanding one, and no one has the right to call the end of two kinds of timings as a time, without good reason, and for no reason.’”
