عَنْهُ عَنْ سُلَيْمَانَ بْنِ دَاوُدَ عَنْ عَبْدِ اَللَّهِ بْنِ وَضَّاحٍ قَالَ: كَتَبْتُ إِلَى اَلْعَبْدِ اَلصَّالِحِ عَلَيْهِ اَلسَّلاَمُ يَتَوَارَى اَلْقُرْصُ وَ يُقْبِلُ اَللَّيْلُ ثُمَّ يَزِيدُ اَللَّيْلُ اِرْتِفَاعاً وَ تَسْتَتِرُ عَنَّا اَلشَّمْسُ وَ تَرْتَفِعُ فَوْقَ اَلْجَبَلِ حُمْرَةٌ وَ يُؤَذِّنَ عِنْدَنَا اَلْمُؤَذِّنُونَ فَأُصَلِّي حِينَئِذٍ وَ أُفْطِرُ إِنْ كُنْتُ صَائِماً أَوْ أَنْتَظِرُ حَتَّى تَذْهَبَ اَلْحُمْرَةُ اَلَّتِي فَوْقَ اَلْجَبَلِ فَكَتَبَ إِلَيَّ« أَرَى لَكَ أَنْ تَنْتَظِرَ حَتَّى تَذْهَبَ اَلْحُمْرَةُ وَ تَأْخُذَ بِالْحَائِطَةِ لِدِينِكَ»
From him, from Sulayman ibn Dawud, from Abdullah ibn Waddah who said:
I wrote to the Righteous Servant (Abd al Salih عليه السلام), peace be upon him: “The disk disappears and the night approaches, then the night continues to rise, and the sun is hidden from us, and above the mountain a redness appears, and the callers to prayer make the Adhan among us; should I pray at that time and break my fast if I am fasting, or should I wait until the redness above the mountain disappears?” So Imam عليه السلام wrote to me: "I see for you that you should wait until the redness disappears and take precaution for your religion."
