1819 - وَ سَأَلَ أَبُو بَصِيرٍ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ : عَنِ اَلصَّائِمِ اَلْمُتَطَوِّعِ تَعْرِضُ لَهُ اَلْحَاجَةُ قَالَ «هُوَ بِالْخِيَارِ مَا بَيْنَهُ وَ بَيْنَ اَلْعَصْرِ وَ إِنْ مَكَثَ حَتَّى اَلْعَصْرِ ثُمَّ بَدَأَ لَهُ أَنْ يَصُومَ وَ لَمْ يَكُنْ نَوَى ذَلِكَ فَلَهُ أَنْ يَصُومَ ذَلِكَ اَلْيَوْمَ إِنْ شَاءَ.
Hadith.1819 - Abu Basir asked Abu Abdullah (Imam Jafar ibn Muhammad Al-Sadiq (as)) about a person observing an optional fast who encounters a need to break it. Imam (as) said: "He has the choice until the time of Asr. If he waits until Asr and then decides to fast without having made the intention earlier, he may still fast that day if he wishes."
