2ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنِ الْعَلاَءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ رَأَيْتُ أَبَا جَعْفَرٍ (عَلَيْهِ الْسَّلام) صَلَّى فِي إِزَارٍ وَاحِدٍ لَيْسَ بِوَاسِعٍ قَدْ عَقَدَهُ عَلَى عُنُقِهِ فَقُلْتُ لَهُ مَا تَرَى لِلرَّجُلِ يُصَلِّي فِي قَمِيصٍ وَاحِدٍ فَقَالَ إِذَا كَانَ كَثِيفاً فَلاَ بَأْسَ بِهِ وَالْمَرْأَةُ تُصَلِّي فِي الدِّرْعِ وَالْمِقْنَعَةِ إِذَا كَانَ الدِّرْعُ كَثِيفاً يَعْنِي إِذَا كَانَ سَتِيراً قُلْتُ رَحِمَكَ الله الأمَةُ تُغَطِّي رَأْسَهَا إِذَا صَلَّتْ فَقَالَ لَيْسَ عَلَى الأمَةِ قِنَاعٌ.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from fro al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “I once saw abu Ja‘far , perform Salah (prayer) wearing a loincloth, not very large, secured to his neck by a knot. I then asked him (the Imam) about a man who performs Salah (prayer) in one shirt. He (the Imam) said, ‘It is not an offense if it is woven densely, and a woman performs Salah (prayer) in a loose outer garment and veil, if the outer garment is densely woven, that is, provides covering.’ I then asked saying, ‘Allah has granted you blessings, is a slave-girl to cover her head in Salah (prayer)? He (the Imam) said, ‘A slave girl is not required to have a veil.’”
