415 - وَ سُئِلَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلرَّجُلِ يَكُونُ لَهُ اَلْقَمِيصُ أَ يُكَفَّنُ فِيهِ فَقَالَ «اِقْطَعْ أَزْرَارَهُ» قُلْتُ وَ كُمَّهُ قَالَ «لاَ إِنَّمَا ذَلِكَ إِذَا قُطِعَ لَهُ وَ هُوَ جَدِيدٌ لَمْ يُجْعَلْ لَهُ أَكْمَامٌ فَأَمَّا إِذَا كَانَ ثَوْباً لَبِيساً فَلاَ يُقْطَعُ مِنْهُ إِلاَّ اَلْأَزْرَارُ.
Hadith.415 - Imam Jafar ibn Muhammad Al-Sadiq 
was asked about whether a man should be shrouded in his shirt (Qamis).
Imam said: "Remove its buttons."
I asked: "And the sleeves?"
Imam said: "No, that is only necessary if it is made new for him, in which case it should have no sleeves. However, if it is an already-worn garment, only the buttons need to be removed."
