مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ بَكْرِ بْنِ صَالِحٍ عَنْ عَبْدِ اللَّهِ بْنِ إِبْرَاهِيمَ الْجَعْفَرِيِّ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ
بِأَيِّ شَيْءٍ يَأْمُرُكُمْ أَطِبَّاؤُكُمْ فِي الْأُتْرُجِّ فَقُلْتُ يَأْمُرُونَنَا أَنْ نَأْكُلَهُ قَبْلَ الطَّعَامِ فَقَالَ إِنِّي آمُرُكُمْ بِهِ بَعْدَ الطَّعَامِ .
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Bakr ibn Salih from ‘Abd Allah ibn Ibrahim al-Ja‘fariy who has said the following:
“Abu ’Abd Allah 
, once asked, ‘What do your physicians recommend for you about citron?’ I replied, ‘They recommend us to eat citron before food.’ He (the Imam) said, ’I recommend you to eat it after food.’”
