عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ يَاسِرٍ الْخَادِمِ عَنِ الرِّضَا ( عليه السلام ) قَالَ لَا بَأْسَ بِكَثْرَةِ شُرْبِ الْمَاءِ عَلَى الطَّعَامِ وَ لَا تُكْثِرْ مِنْهُ عَلَى غَيْرِهِ وَ قَالَ أَ رَأَيْتَ لَوْ أَنَّ رَجُلًا أَكَلَ مِثْلَ ذَا وَ جَمَعَ يَدَيْهِ كِلْتَيْهِمَا لَمْ يَضُمَّهُمَا وَ لَمْ يُفَرِّقْهُمَا ثُمَّ لَمْ يَشْرَبْ عَلَيْهِ الْمَاءَ كَانَ يَنْشَقُّ مَعِدَتُهُ .
3. Ali ibn Ibrahim has narrated from his father from Yasar al-Khadim who has said the following: “Abu al-Hassan, al-Rida’ (a.s.), has said, ‘It is not harmful to drink water after food but do not drink water excessively on things other than food.’ He (the Imam) said, ‘Consider, the man who eats this much’ — he brought his hands close to each other and did not join them and did not keep them much apart - ‘then he does not drink water, his stomach may burst.’”
