Hadith 3691940 - وَ رَوَى مُحَمَّدُ بْنُ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ قَالَ: قُلْتُ لِأَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ آمُرُ اَلْجَارِيَةَ لِتَنْظُرَ إِلَى اَلْفَجْرِ فَتَقُولُ لَمْ يَطْلُعْ بَعْدُ فَآكُلُ ثُمَّ أَنْظُرُ فَأَجِدُهُ قَدْ كَانَ طَلَعَ حِينَ نَظَرَتْ قَالَ «اِقْضِهِ أَمَا إِنَّكَ لَوْ كُنْتَ أَنْتَ اَلَّذِي نَظَرْتَ لَمْ يَكُنْ عَلَيْهِ شَيْءٌ.
Hadith.1940 - Muhammad ibn Abi Umayr narrated from Mu'awiyah ibn Ammar, who said:
"I asked Abu Abdullah (as): 'I instruct a servant girl to check for the dawn, and she tells me that it has not risen yet, so I eat. Then I check and find that it had actually risen when she looked.'
Imam (as) said: 'Make up that day. However, if you had been the one to check and it happened, there would be nothing upon you.'"
